FIELD OF THE INVENTION

The present invention provides methods for genetic modification and regulation of expression status of endogenous genes and other genomic loci using engineered DNA binding proteins.

BACKGROUND OF THE INVENTION

Many, perhaps most, physiological and pathophysiological processes can be controlled by the selective up or down regulation of gene expression. Examples of pathologies that might be controlled by selective regulation include the inappropriate expression of proinflammatory cytokines in rheumatoid arthritis, under-expression of the hepatic LDL receptor in hypercholesterolemia, over-expression of proangiogenic factors and under-expression of antiangiogenic factors in solid tumor growth, to name a few. In addition, pathogenic organisms such as viruses, bacteria, fungi, and protozoa could be controlled by altering gene expression of their host cell. Thus, there is a clear unmet need for therapeutic approaches that are simply able to up-regulate beneficial genes and down-regulate disease causing genes.

In addition, simple methods allowing the selective over- and under-expression of selected genes would be of great utility to the scientific community. Methods that permit the regulation of genes in cell model systems, transgenic animals and transgenic plants would find widespread use in academic laboratories, pharmaceutical companies, genomics companies and in the biotechnology industry.

Gene expression is normally controlled through alterations in the function of sequence specific DNA binding proteins called transcription factors. They act to influence the efficiency of formation or function of a transcription initiation complex at the promoter. Transcription factors can act in a positive fashion (activation) or in a negative fashion (repression).

Transcription factor function can be constitutive (always “on”) or conditional. Conditional function can be imparted on a transcription factor by a variety of means, but the majority of these regulatory mechanisms depend of the sequestering of the factor in the cytoplasm and the inducible release and subsequent nuclear translocation, DNA binding and activation (or repression). Examples of transcription factors that function this way include progesterone receptors, sterol response element binding proteins (SREBPs) and NF-kappa B. There are examples of transcription factors that respond to phosphorylation or small molecule ligands by altering their ability to bind their cognate DNA recognition sequence (Hou et al., Science 256:1701 (1994); Gossen & Bujard, Proc. Nat'l Acad Sci 89:5547 (1992); Oligino et al., Gene Ther. 5:491-496 (1998); Wang et al., Gene Ther. 4:432-441 (1997); Neering et al., Blood 88:1147-1155 (1996); and Rendahl et al., Nat. Biotechnol. 16:757-761 (1998)).

Recombinant transcription factors comprising the DNA binding domains from zinc finger proteins (“ZFPs”) have the ability to regulate gene expression of endogenous genes (see, e.g., U.S. Pat. Nos. 6,534,261; 6,599,692; 6,503,717; 6,689,558; 7,067,317; 7,262,054). Clinical trials using these engineered transcription factors containing zinc finger proteins have shown that these novel transcription factors are capable of treating various conditions. (see, e.g., Yu et al. (2006) FASEB J. 20:479-481).

Another major area of interest in genome biology, especially in light of the determination of the complete nucleotide sequences of a number of genomes, is the targeted alteration of genome sequences. Such targeted cleavage events can be used, for example, to induce targeted mutagenesis, induce targeted deletions of cellular DNA sequences, and facilitate targeted recombination at a predetermined chromosomal locus. See, for example, United States Patent Publications 20030232410; 20050208489; 20050026157; 20050064474; 20060188987; 2008015996, and International Publication WO 2007/014275, the disclosures of which are incorporated by reference in their entireties for all purposes. See, also, Santiago et al. (2008) Proc Natl Acad Sci USA 105:5809-5814; Perez et al. (2008) Nat Biotechnol 26:808-816 (2008).

Artificial nucleases, which link the cleavage domain of a nuclease to a designed DNA-binding protein (e.g., zinc-finger protein (ZFP) linked to a nuclease cleavage domain such as from FokI), have been used for targeted cleavage in eukaryotic cells. For example, zinc finger nuclease-mediated genome editing has been shown to modify the sequence of the human genome at a specific location by (1) creation of a double-strand break (DSB) in the genome of a living cell specifically at the target site for the desired modification, and by (2) allowing the natural mechanisms of DNA repair to “heal” this break.

To increase specificity, the cleavage event is induced using one or more pairs of custom-designed zinc finger nucleases that dimerize upon binding DNA to form a catalytically active nuclease complex. In addition, specificity has been further increased by using one or more pairs of zinc finger nucleases that include engineered cleavage half-domains that cleave double-stranded DNA only upon formation of a heterodimer. See, e.g., U.S. Patent Publication No. 20080131962, incorporated by reference herein in its entirety.

The double-stranded breaks (DSBs) created by artificial nucleases have been used, for example, to induce targeted mutagenesis, induce targeted deletions of cellular DNA sequences, and facilitate targeted recombination at a predetermined chromosomal locus. See, for example, United States Patent Publications 20030232410; 20050208489; 20050026157; 20050064474; 20060188987; 20060063231; 20070218528; 20070134796; 20080015164 and International Publication Nos. WO 07/014275 and WO 2007/139982, the disclosures of which are incorporated by reference in their entireties for all purposes. Thus, the ability to generate a DSB at a target genomic location allows for genomic editing of any genome.

There are two major and distinct pathways to repair DSBs—homologous recombination and non-homologous end-joining (NHEJ). Homologous recombination requires the presence of a homologous sequence as a template (known as a “donor”) to guide the cellular repair process and the results of the repair are error-free and predictable. In the absence of a template (or “donor”) sequence for homologous recombination, the cell typically attempts to repair the DSB via the error-prone process of NHEJ.

The plant pathogenic bacteria of the genus Xanthomonas are known to cause many diseases in important crop plants. Pathogenicity of Xanthomonas depends on a conserved type III secretion (T3 S) system which injects more than 25 different effector proteins into the plant cell. Among these injected proteins are transcription activator-like effectors “TALE” or “TAL-effectors”) which mimic plant transcriptional activators and manipulate the plant transcriptome (see Kay et at (2007) Science 318:648-651). These proteins contain a DNA binding domain and a transcriptional activation domain. One of the most well characterized TALEs is AvrBs3 from Xanthomonas campestris pv. Vesicatoria (see Bonas et at (1989) Mol Gen Genet 218: 127-136 and WO2010079430). TALEs contain a centralized repeat domain that mediates DNA recognition, with each repeat unit containing approximately 33-35 amino acids specifying one target base. TALEs also contain nuclear localization sequences and several acidic transcriptional activation domains (for a review see Schornack S, et at (2006) J Plant Physiol 163(3): 256-272). In addition, in the phytopathogenic bacteria Ralstonia solanacearum two genes, designated brg11 and hpx17 have been found that are homologous to the AvrBs3 family of Xanthomonas in the R. solanacearum biovar 1 strain GMI1000 and in the biovar 4 strain RS1000 (See Heuer et at (2007) Appl and Envir Micro 73(13): 4379-4384). These genes are 98.9% identical in nucleotide sequence to each other but differ by a deletion of 1,575 bp in the repeat domain of hpx17. However, both gene products have less than 40% sequence identity with AvrBs3 family proteins of Xanthomonas.

DNA-binding specificity of these TALEs depends on the sequences found in the tandem TALE repeat units. The repeated sequence comprises approximately 33-35 amino acids and the repeats are typically 91-100% homologous with each other (Bonas et al, ibid). There appears to be a one-to-one correspondence between the identity of the hypervariable diresidues at positions 12 and 13 with the identity of the contiguous nucleotides in the TALE's target sequence (see Moscou and Bogdanove, (2009) Science 326:1501 and Boch et at (2009) Science 326:1509-1512). These two adjacent amino acids are referred to as the Repeat Variable Diresidue (RVD). Experimentally, the natural code for DNA recognition of these TALEs has been determined such that an HD sequence at positions 12 and 13 leads to a binding to cytosine (C), NG binds to T, NI to A, NN binds to G or A, and NG binds to T. These specificity-determining TALE repeat units have been assembled into proteins with new combinations of the natural TALE repeat units and altered numbers of repeats, to make variant TALE proteins. When in their native architecture, these variants are able to interact with new sequences and activate the expression of a reporter gene in plant cells (Boch et al., ibid.). However, these proteins maintain the native (full-length) TALE protein architecture and only the number and identity of the TALE repeat units within the construct were varied. Entire or nearly entire TALE proteins have also been fused to a nuclease domain from the FokI protein to create a TALE-nuclease fusion protein (“TALEN”), and these TALENs have been shown to cleave an episomal reporter gene in yeast cells. (Christian et al. (2010) Genetics 186(2): 757-61; Li et al. (2011a) Nucleic Acids Res. 39(1):359-372). Such constructs could also modify endogenous genes in yeast cells to quantifiable levels and could modify endogenous genes in mammalian and plant cells to detectable, but unquantifiable levels when appropriate sequence amplification schemes are employed. See, Li et al. (2011b) Nucleic Acids Res. epub doi:10.1093/nar/gkr188; Cermak et al. (2011) Nucleic Acids Res. epub doi:10.1093/nar/gkr218. The fact that a two step enrichment scheme was required to detect activity in plant and animal cells indicates that fusions between nearly entire TALE proteins and the nuclease domain from the FokI protein do not efficiently modify endogenous genes in plant and animal cells. In other words, the peptide used in these studies to link the TALE repeat array to the FokI cleavage domain does not allow efficient cleavage by the FokI domain of endogenous genes in higher eukaryotes. These studies therefore highlight the need to develop compositions that can be used connect a TALE array with a nuclease domain that would allow for highly active cleavage in endogenous eukaryotic settings.

There remains a need for engineered DNA binding domains to increase the scope, specificity and usefulness of these binding proteins for a variety of applications including engineered transcription factors for regulation of endogenous genes in a variety of cell types and engineered nucleases that can be similarly used in numerous models, diagnostic and therapeutic systems, and all manner of genome engineering and editing applications.

SUMMARY OF THE INVENTION

The present invention thus provides for methods of targeted manipulation of expression state or sequence of endogenous loci. In some embodiments of the invention, the methods of the invention use DNA-binding proteins comprising one or more TALE-repeat units fused to functional protein domains (collectively “TALE-fusions”), to form engineered transcription factors, engineered nucleases (“TALENs”), recombinases, transposases, integrases, methylases, enzymatic domains and reporters. In some aspects, the polypeptide includes the at least one TALE repeat unit linked to additional TALE protein sequences, for efficient and specific function at endogenous target DNA. These additional sequences, which are linked to the N- and optionally the C-termini of the TALE repeat domain, are also referred to as the “N-cap” and “C-cap” sequences. Thus, the invention provides polypeptides comprising one or more (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 20 or more) TALE repeat and/or half-repeat units.

Thus, in one aspect, provided herein is a DNA-binding polypeptide comprising at least one TALE repeat unit (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 or more repeat unit(s)). The polypeptide typically includes an N-cap sequence (polypeptide) of any length that supports DNA-binding function of the TALE repeat(s) or functional activity of the TALE fusion protein. Optionally, the polypeptide may also include a C-cap sequence (polypeptide), for example a C-cap sequence of less than approximately 250 amino acids (C+230 C-cap; from residue C−20 to residue C+230). In addition, in certain embodiments, at least one of the TALE repeat units of the TALE polypeptides as described herein include repeat variable di-residue (RVD) regions that are atypical. The TALE repeat unit may be a wild-type domain isolated from Xanthomonas, Ralstonia or another related bacteria and/or may be engineered in some manner (e.g., may be non-naturally occurring). In certain embodiments, at least one TALE repeat unit is engineered (e.g., non-naturally occurring, atypical, codon optimized, combinations thereof, etc.). In certain embodiments, one or more amino acids in the TALE repeat domain (e.g., an RVD within one of the TALE repeats) are altered such that the domain binds to a selected target sequence (typically different from the target sequence bound by a naturally occurring TALE DNA binding domain). In other embodiments, at least one TALE repeat unit is modified at some or all of the amino acids at positions 4, 11, 12, 13 or 32 within the TALE repeat unit. In some embodiments, at least one TALE repeat unit is modified at 1 or more of the amino acids at positions 2, 3, 4, 11, 12, 13, 21, 23, 24, 25, 26, 27, 28, 30, 31, 32, 33, 34, or 35 within one TALE repeat unit. In other embodiments, the nucleic acid encoding the TALE repeat is modified such that the DNA sequence is altered but the amino acid sequence is not. In some embodiments, the DNA modification is for the purposes of codon optimization. In further embodiments, at least one TALE repeat unit is altered by combinations of the above described modifications. In some embodiments, TALE proteins comprising several modified TALE repeat units are provided. Combinations of naturally occurring and non-naturally occurring TALE repeat units are also provided. In a preferred embodiment, the TALE protein (wild-type or engineered) further comprises N-cap and optionally the C-cap sequences for efficient and specific function at endogenous target DNA. In some embodiments, the N-cap comprises residues N+1 to N+136 (see FIG. 1B for a description of the residue numbering scheme), or any fragment thereof. In other embodiments, the C-cap comprises residues C−20 to C+28, C−20 to C+39, C−20 to C+55, or C−20 to C+63 or any fragments of the full length TALE C-terminus thereof. In certain embodiments, the polypeptide comprising the TALE repeat domain, as well as an N-cap and optional C-cap sequences, further comprises a regulatory or functional domain, for example, a transcriptional activator, transcriptional repressor, nuclease, recombinase, transposase, integrase, methylase or the like.

Polynucleotides encoding these proteins are also provided as are pharmaceutical compositions. In addition, the invention includes host cells, cell lines and transgenic organisms (e.g., plants, fungi, animals) comprising these proteins/polynucleotides and/or modified by these proteins (e.g., genomic modification that is passed onto the progeny). Exemplary cells and cell lines include animal cells (e.g., mammalian, including human, cells such as stem cells), plant cells, bacterial cells, protozoan cells, fish cells, or fungal cells. In another embodiment, the cell is a mammalian cell. Methods of making and using these proteins and/or polynucleotides are also provided.

In one aspect, provided herein are fusion proteins comprising one or more engineered TALE repeat units, an N-cap, and an optional C-cap sequence, operatively linked to one or more heterologous polypeptide domains, for example functional (regulatory) domains. Libraries comprising modules of TALE repeats are provided as are optional structured or flexible linkers for connecting the engineered TALE repeats to the functional protein domain of interest. The functional protein domain (e.g., transcriptional activator, repressor, or nuclease) may be positioned at the C- or N-termini of the fusion protein. Methods of making fusion proteins as described herein are also provided.

The present invention also provides a method for identifying suitable target sequences (sites) for engineered TALE fusion proteins. In some embodiments, a target site identified has an increased number of guanine nucleotides (“G”) as compared to a natural TALE target sequence. In other embodiments, the target does not require flanking thymidine nucleotides (“T”), as typical in naturally occurring TALE proteins. In some embodiments, the RVDs selected for use in the engineered TALE protein contains one or more NK (asparagine-lysine) RVDs for the recognition of G nucleotides in the target sequence. Additionally provided in this invention are novel (non-naturally occurring) RVDs, differing from those found in nature, which are capable of recognizing nucleotide bases. Non-limiting examples of atypical or non-naturally occurring RVDs (amino acid sequences at positions 12 and 13 of the TALE repeat unit) include RVDs as shown in Tables 27A, 27B and 29, for example, VG and IA to recognize T, RG to recognize A and T, and AA to recognize A, C, and T are provided. Also provided are RVDs capable of interacting equally with all nucleotide bases (e.g. A, C, T, and G). Additional RVDs useful in the compositions and methods described herein are shown in Table 27.

Also provided by the invention are methods to constrain, or not constrain, by the user's choice, the distance or gap spacing between the two target sites on a nucleic acid that is subject to modification by a TALE-nuclease (“TALEN”) heterodimer. In some embodiments, the gap spacing is constrained to 12-13 base pairs, while in other embodiments, the engineered TALEN is designed to cleave DNA targets comprising a gap spacing of between 12 to 21 base pairs. In some embodiments, the TALEN heterodimer is designed to cleave a sequence comprising a gap of between 1 and 34 nucleotides between each monomer binding site. In still more embodiments, the TALEN is constrained to cleave a target with a 12 or 13 base pair gap by utilizing a TALEN architecture comprising the +28 C-terminal truncation (C+28 C-cap). In other embodiments, the designed TALEN is made to cleave a target nucleic acid comprising a 12 to 21 base pair gap spacing using a TALEN architecture comprising the +63 C-terminal truncation, which increases the likelihood of being able to identify a suitable TALEN target site due to the flexibility in gap spacing requirements. In some embodiments, the TALEN has an engineered R1/2 repeat such that the R1/2 repeat is capable of targeting nucleotide bases other than T.

In another aspect, the present invention provides a vector for an engineered TALE DNA binding domain fusion wherein the vector comprises the TALE N-cap and C-cap sequences flanking the TALE repeat sequences as well as locations to allow for the cloning of multiple TALE repeat units, linker sequences, promoters, selectable markers, polyadenylation signal sites, functional protein domains and the like. Also provided by the invention herein is a method for the construction of a modular archive library including at least one TALE-repeat unit (e.g., engineered) for ready assembly of specific TALE DNA binding domain domains and fusion proteins comprising these domains (e.g., TALENs).

In yet another aspect, the present invention provides a method of modulating the expression of an endogenous cellular gene in a cell, the method comprising the step of: contacting a first target site in the endogenous cellular gene with a first engineered TALE fused to a functional domain (e.g., transcriptional modulator domain), thereby modulating expression of the endogenous cellular gene. In another aspect, the present invention provides a method of modulating expression of an endogenous cellular gene in a cell, the method comprising the step of: contacting a target site in the endogenous cellular gene with a fusion TALE protein wherein the TALE comprises an engineered TALE repeat domain such that the TALE has specificity for a desired sequence. In some embodiments, the modulatory effect is to activate the expression of the endogenous gene. In some embodiments, the expression of the endogenous gene is inhibited. In yet another embodiment, activation or repression of the endogenous gene is modulated by the binding of a TALE fusion protein such that an endogenous activator or repressor cannot bind to the regulator regions of the gene of interest.

In one embodiment, the step of contacting further comprises contacting a second target site in an endogenous cellular gene with a second engineered TALE fusion protein, thereby modulating expression of the second endogenous cellular gene. In another embodiment, the first and second target sites are adjacent. In certain embodiments, the first and second target sites are in different genes, for example to modulate expression of two or more genes using TALE-transcription factors. In other embodiments, the first and second target sites are in the same gene, for example when a pair of TALEN fusion proteins is used to cleave in the same gene. The first and second target sites are separated by any of base pairs (“gap size”), for example, 1 to 20 (or any number therebetween) or even more base pairs. In another embodiments, the step of contacting further comprises contacting more than two target sites. In certain embodiments, two sets of target sites are contacted by two pairs of TALENs, and are used to create a specific deletion or insertion at the two sets of targets. In another embodiment, the first TALE protein is a fusion protein comprising a regulatory or functional domain. In another embodiment, the first TALE protein is a fusion protein comprising at least two regulatory or functional domains. In another embodiment, the first and second TALE proteins are fusion proteins, each comprising a regulatory domain. In another embodiment, the first and second TALE proteins are fusion proteins, each comprising at least two regulatory domains. The one or more functional domains may be fused to either (or both) ends of the TALE protein. Any of the TALE fusions proteins can be provided as polynucleotides encoding these proteins.

In yet another aspect, the invention provides compositions for C-caps linking a nuclease domain to a TALE repeat domain as described herein, wherein the resulting fusion protein exhibits highly active nuclease function. In some embodiments the C-cap comprises peptide sequence from native TALE C-terminal flanking sequence. In other embodiments, the C-cap comprises peptide sequence from a TALE repeat domain. In yet another embodiment, the C-cap comprises sequences not derived from TALE proteins. C-caps may also exhibit a chimeric structure, for example comprising peptide sequences from native TALE C-terminal flanking sequence and/or TALE repeat domains and/or non-TALE polypeptides.

In any of the compositions or methods described herein, the regulatory or functional domain may be selected from the group consisting of a transcriptional repressor, a transcriptional activator, a nuclease domain, a DNA methyl transferase, a protein acetyltransferase, a protein deacetylase, a protein methyltransferase, a protein deaminase, a protein kinase, and a protein phosphatase. In some aspects, the functional domain is an epigenetic regulator. In plants, such a TALE fusion can be removed by out-crossing using standard techniques. In such an embodiment, the fusion protein would comprise an epigenetic regulator such as, by non-limiting example, a histone methyltransferase, DNA methyltransferase, or histone deacetylase. See for example, co-owned U.S. Pat. No. 7,785,792.

Thus, in some aspects, the TALE fusion protein comprises a TALE-repeat domain fused to a nuclease domain (a “TALEN”). As noted above, in some embodiments the TALE repeat domain is further fused to an N-cap sequence and, optionally, a C-cap sequence. In other embodiments, the nuclease domain is connected to either the amino terminus of the N-cap or carboxy terminus of the C-cap via linker peptide sequences that provide efficient catalytic function of the nuclease domain. The nuclease domain may be naturally occurring or may be engineered or non-naturally occurring. In some embodiments, the nuclease domain is derived from a Type IIS nuclease (e.g. FokI). In other embodiments, the TALE DNA binding domain is operably linked to a Bfi I nuclease domain. In some embodiments, the FokI domain is a single chain nuclease domain, comprising two cleavage half domains, and in others it is a FokI cleavage half domain. In some aspects of the invention, a single TALEN protein is used by itself to induce a double strand break in a target DNA, while in others, the TALEN is used as part of a pair of nucleases. In some embodiments, the pair comprises two TALENs comprising FokI half domains, wherein the pairing of the FokI half domains is required to achieve DNA cleavage, while in other cases the TALEN protein is used in combination with a zinc-finger nuclease wherein pairing of the two FokI cleavage domains is required to achieve DNA cleavage. In some embodiments, the TALE DNA binding domain is fused to a zinc finger to make a zing finger/TALE hybrid DNA binding domain. In some instances, the hybrid DNA binding domain is able to skip interacting with internal stretches of DNA bases within the DNA target binding site. In some embodiments, the FokI domains are able to form homodimers, and in other instances, heterodimerization of two non-identical FokI cleavage domains from each member of the TALEN pair is required for targeted cleavage activity. In these heterodimeric TALEN pairs, two FokI domains of the same type are not able to productively homodimerize. In other embodiments, a TALEN pair is used wherein one FokI cleavage domain is inactive such that pairing may occur, but the target DNA is nicked to produce a cut on one strand of the DNA molecule rather than cleaving both strands.

In any of the compositions or methods described herein, the TALE fusion protein may be encoded by a TALE fusion protein nucleic acid. In certain embodiments, the sequence encoding the TALE fusion protein is operably linked to a promoter. Thus, in certain embodiments, the methods of modulating endogenous gene expression or genomic modification further comprises the step of first administering the nucleic acid encoding the TALE protein to the cell. The TALE-fusion protein may be expressed from an expression vector such as a retroviral expression vector, an adenoviral expression vector, a DNA plasmid expression vector, or an AAV expression vector. In some embodiments, the expression vector is a lentiviral vector, and in some of these embodiments, the lentiviral vector is integrase-defective.

Also provided in the invention are TALENs (e.g., TALEN pairs) specific to any desired target locus (e.g., endogenous gene) in any cell type. Non-limiting examples include TALENs specific for NTF3, VEGF, CCR5, IL2Rγ, BAX, BAK, FUT8, GR, DHFR, CXCR4, GS, Rosa26, AAVS1 (PPP1R12C), MEW genes, PITX3, ben-1, Pou5F1 (OCT4), C1, RPD1, etc.

The TALE-repeat domains as described herein may bind to a target site that is upstream of, or adjacent to, a transcription initiation site of the endogenous cellular gene. Alternatively, the target site may be adjacent to an RNA polymerase pause site downstream of a transcription initiation site of the endogenous cellular gene. In still further embodiments, the TALE fusion protein (e.g., a TALEN) binds to a site within the coding sequence of a gene or in a non-coding sequence within or adjacent to the gene, such as for example, a leader sequence, trailer sequence or intron, or within a non-transcribed region, either upstream or downstream of the coding region.

In another aspect, described herein is a method for cleaving one or more genes of interest in a cell, the method comprising: (a) introducing, into the cell, one or more one or more TALEN protein(s) (or polynucleotides encoding the TALENs) that bind to a target site in the one or more genes under conditions such that the TALEN protein(s) is (are) expressed and the one or more genes are cleaved. In embodiments in which two or more TALEN proteins are introduced, one, some or all can be introduced as polynucleotides or as polypeptides. In some aspects, said gene cleavage results in the functional disruption of the targeted gene. Cleavage of the targeted DNA may be followed by NHEJ wherein small insertions or deletions (indels) are inserted at the site of cleavage. These indels then cause functional disruption through introduction of nonspecific mutations at the cleavage location.

In yet another aspect, described herein is a method for introducing an exogenous sequence into the genome of a cell, the method comprising the steps of: (a) introducing, into the cell, one or more TALEN protein(s) (or polynucleotides encoding the TALEN protein(s)) that bind to a target site in a target gene under conditions such that the TALEN protein(s) is (are) expressed and the one or more target sites within the genes are cleaved; and (b) contacting the cell with an exogenous polynucleotide; such that cleavage of the DNA target site(s) stimulates integration of the exogenous polynucleotide into the genome by homologous recombination. In certain embodiments, the exogenous polynucleotide is integrated physically into the genome. In other embodiments, the exogenous polynucleotide is integrated into the genome by copying of the exogenous sequence into the host cell genome via specialized nucleic acid replication processes associated with homology-directed repair (HDR) of the double strand break. In yet other embodiments, integration into the genome occurs through non-homology dependent targeted integration (e.g. “end-capture”). In some embodiments, the exogenous polynucleotide comprises a recombinase recognition site (e.g. loxP or FLP) for recognition by a cognate recombinase (e.g. Cre or FRT, respectively). In certain embodiments, the exogenous sequence is integrated into the genome of a small animal (e.g. rabbit or rodent such as mouse, rat, etc.). In one embodiment, the TALE-fusion protein comprises a transposase, recombinase or integrase, wherein the TALE-repeat domain has been engineered to recognize a specifically desired target sequence. In some embodiments, TALE polypeptides are used. In some aspects, the TALE-fusion protein comprises a transposase or integrase and is used for the development of a CHO-cell specific transposase/integrase system.

In some embodiments, the TALE-fusion protein comprises a methyltransferase wherein the TALE-repeat domain has been engineered to recognize a specifically desired target sequence. In some embodiments, the TALE-repeat domain is fused to a subunit of a protein complex that functions to effect epigenetic modification of the genome or of chromatin.

In yet further embodiments, that TALE-fusion further comprises a reporter or selection marker wherein the TALE-repeat domain has been engineered to recognize a specifically desired target sequence. In some aspects, the reporter is a fluorescent marker, while in other aspects, the reporter is an enzyme.

In another aspect, described herein are compositions comprising one or more of the TALE-fusion proteins. In certain embodiments, the composition comprises one or more TALE-fusion proteins in combination with a pharmaceutically acceptable excipient.

In another aspect, described herein is a TALE-fusion protein expression vector comprising a polynucleotide, encoding one or more TALE-fusion proteins described herein, operably linked to a promoter (e.g., constitutive, inducible, tissue-specific or the like).

In another aspect, described herein is a host cell comprising one or more TALE-fusion proteins and/or one or more polynucleotides (e.g., expression vectors encoding TALE-fusion proteins as described herein. In certain embodiments, the host cell further comprises one or more zinc finger proteins and/or ZFP encoding vectors. The host cell may be stably transformed or transiently transfected or a combination thereof with one or more of these protein expression vectors.

Another aspect provided by the invention is a method for identifying a suitable nucleic acid target for TALE binding. In some embodiments, a target is chosen based upon its similarity to target sites used by typical, naturally occurring TALE proteins. In other embodiments, a target is selected that is not utilized by typical, naturally occurring TALE proteins because the engineered TALE proteins have been altered in such a way as to make them able to interact with an atypical, target sequence. In some embodiments, this alteration involves the selection of atypical (non-naturally occurring or rare) RVD sequences. In further embodiments, the atypical RVD used is a ‘NK’ RVD for the recognition of a G residue in the desired target sequence. In other embodiments, targets are selected that contain non-natural ratios of nucleic acid bases because the engineered TALE proteins have been altered in such a way as to make them able to interact with a non-natural ratio of nucleic acid bases. In some embodiments, the ratio of bases in the desired target sequence comprises an unusual number of G residues. In other embodiments, the ratio of bases in the desired target sequence comprises an unusual number of atypical di-nucleotides, tri-nucleotides or tetra-nucleotides. Further provided are design rules for identifying the most optimal targets for TALE-DNA binding interactions. These rules provide guidance on selection of a target site sequence comprising optimal di- and tri-nucleotide pairs. In addition, these rules also provide guidance on less optimal di- and tri-nucleotide pairs so that the artisan may avoid these sequences if desired. Also provided are RVDs able to interact with all nucleotides to provide the user a greater flexibility in choosing target sequences.

These kits may be used to facilitate genomic manipulation by the user and so can provide a TALEN, for example, that will cleave a desired target or a safe harbor locus within a genome. The TALEN may be provided either as nucleic acid (e.g. DNA or RNA) or may be provided as protein. In some instances, the protein may be formulated to increase stability, or may be provided in a dried form. In some instances, the kits are used for diagnostic purposes.

BRIEF DESCRIPTION OF THE DRAWINGS

FIGS. 1A and 1B depict a TALE protein. FIG. 1A shows a schematic of the domain structure of a TALE protein (not drawn to scale). ‘N’ and ‘C’ indicate the amino and carboxy termini, respectively. The TALE repeat domain, N-cap and C-cap are labeled and the residue numbering scheme for the N-cap and C-cap in this protein are indicated. “R0” represents the 34 amino acids preceding the first tandem TALE repeat that may share some structural homology with the TALE repeat units and that may specify thymine in a DNA target sequence. “R_(1/2)” denotes the C-terminal TALE “half-repeat,” which is a 20 residue peptide sequence (with residues numbered from C−20 to C−1) with homology to the first 20 residues of a typical TALE repeat. NLS is the nuclear localization sequence. AD is the acidic activation domain. FIG. 1B (SEQ ID NO:135) shows the primary sequence of a cloned natural TALE protein (hereinafter referred to as “TALE13”) that was isolated with a cloning scheme designed to delete the N-terminal 1-152 amino acid residues. The N-cap and C-cap are indicated by a thick black line below the sequence; positions N+1 and N+136 in the N-cap and positions C+1 and C+278 in the C-cap are indicated. The half repeat is the first 20 residues of the C-cap and ends immediately prior to the position indicated as “C+1”. Underlined residues in the TALE repeats and half repeat indicate amino acids (RVDs) that specify the DNA nucleotide contacted by the repeat during target binding.

FIGS. 2A and 2B show the reporter construct for use with the predicted target of TALE13 (TR13). FIG. 2A (SEQ ID NO:136) shows a schematic of the reporter vector indicating the cloning sites used for inserting 1-4 TR13 targets into the vector. The region in italics is the promoter region for the luciferase gene. FIG. 2B (SEQ ID NOS 547 and 137, respectively, in order of appearance) shows the linker sequence used containing two TR13 targets.

FIGS. 3A and 3B show a schematic of the reporter construct containing 0-4 TR13 targets (FIG. 3A) and synergistic reporter gene activation by TALE13-VP16 fusion protein (TR13-VP16, TALE13 linked with an activation domain from VP16) on the luciferase reporter constructs containing 1 to 4 multiple TR13 targets, indicated as R13×1 to R13×4, respectively (FIG. 3B). pGL3 is the control reporter vector lacking any TR13 target elements.

FIGS. 4A and 4B show reporter gene activation by TALE VP16 fusion proteins. FIG. 4A is a schematic of the TALE proteins, with or without the addition of VP16 domain, as well as the reporter constructs used in the study. R13×2 indicates the construct where two of the TALE13 (TR13) targets are inserted while R15×2 indicates the construct where two of the TALE15 (TR15) targets are inserted. FIG. 4B shows the reporter gene activation by TALE protein with the VP16 fusion but not by the TALE protein itself. Thus, the natural transcriptional activation domain present in the TALE protein was not functional in mammalian cells in this assay. Moreover, the transcriptional activity observed was specific as the reporter gene activation occurs only when the correct targets are matched with their corresponding TALE VP16 fusions. The cloned TALE13 and TALE15 are indicated as TR13 and TR15 respectively. TR13-VP16 and TR15-VP16 are similar to TR13 and TR15 with the additional VP16 activation domain fused to their C-terminus.

FIGS. 5A and 5B depict positional effects of target sequence placement relative to the promoter. FIG. 5A shows a schematic of the reporter constructs where the target sequences are placed either proximal (R13×4) or distal (R13×4D) to the SV40 promoter. FIG. 5B shows the reporter gene activation by the indicated TALEs. “nR13V-d145C” refers to an expression construct containing the SV40 nuclear localization sequence, the TR13 sequence with 145 amino acid residues deleted from the C-terminus (yielding a C+133 C-cap) and the VP16 activation domain, whereas “R13-VP16” refers to an expression construct containing TALE13 sequence and the VP16 activation domain. As shown, (i) the C-terminal 145 amino acids of the full length TALEs are not required for the reporter gene activation, and (ii) the reporter gene activation is greatest when the target sequences are placed proximal to the promoter sequence.

FIGS. 6A and 6B are graphs depicting the reporter gene (luciferase) activation using a TALE fusion. FIG. 6A depicts the activation of a reporter gene using a fusion protein comprising the engineered TALE 18 protein (R23570 here; referred to as NT-L in later figures). The reporter construct contains 2 copies of the engineered TALE18 targets upstream from the luciferase gene. Activation of this reporter is observed only with R23570V, which contains the 17.5 engineered repeat sequences (17 full TALE repeats and one half repeat), the N- and C-terminal sequences (N-cap and C-cap) flanking the tandem TALE repeats of TR13, and the VP16 activation domain. Deletion of both the N- and C-terminal flanking sequences (N-cap and C-cap) abolishes the activity (compare nR23570S-dNC to mock). nR23570S-dNC contains the SV40 NLS (n), the 17.5 engineered TALE repeat sequences, fused to a single p65 activation domain (S), but is lacking the N- and C-terminal sequences (N-cap and C-cap) from TALE (dNC). The nR23570SS-dNC is the same as nR23570S-dNC except that it has two p65 domains. The R0-VP16 construct is the same as R23570 but lacks the tandem TALE repeats. ‘Mock’ shows the results for an experiment lacking an expression construct. FIG. 6B depicts the activation of an endogenous gene in its chromosomal environment by a fusion protein comprising the engineered (non-naturally occurring) TALE18 domain. The engineered TALE18 (R23570V), which is designed to target to the NTF3 gene, can lead to a substantial increase in the endogenous NTF3 mRNA level. Under the same conditions, the expression of NTF3 mRNA is not affected by either R0-VP16 or GFP. R23570V and R0-VP16 are described as above.

FIGS. 7A through 7D depict additional exemplary NTF3-specific TALE transcription factor fusions. FIG. 7A depicts a diagram of the exemplary proteins and their target in the NTF3 promoter (SEQ ID NO:138). The two TALE transcription factor variants were linked to the VP16 activation domain and expressed in HEK293 cells. The sequence at the bottom shows the promoter-proximal region of human NTF3. Underlined bases indicate the target site for the NT-L TALE repeat domain. The hooked arrow shows the start site of NTF3 transcription. FIG. 7B shows relative NTF3 mRNA levels in HEK293 cells expressing either the top or lower protein sketched in FIG. 7A. “eGFP” indicates cells transfected with a control plasmid that expresses enhanced GFP. Measurements were performed in quadruplicate and error bars indicate standard deviations. FIG. 7C depicts levels of NTF3 protein secreted from HEK293 cells expressing either the top or lower proteins sketched in 7A. Measurements were performed in duplicate using an ELISA assay, and error bars indicate standard deviations. “Neg.” indicates cells transfected with an empty vector control. FIG. 7D shows the RVDs (top row of letters), expected binding site (second row of letters (SEQ ID NO: 548)) and SELEX-derived base frequency matrix for NT-L (graph at bottom). Except for the first and fifth positions in the matrix, the most frequently selected base matches the target locus sequence.

FIGS. 8A and 8B, are graphs depicting the DNA binding ability, as assayed by ELISA, of a series of N- and C-terminal truncations of various engineered TALE DNA binding domains. FIG. 8A depicts the data for an NT3-specific TALE DNA binding domain comprising 9.5 TALE repeats, while FIG. 8B depicts the data for a VEGF-specific TALE DNA binding domain comprising 9.5 TALE repeats. For both sets of data, when the N-terminal truncations were made, the C-terminus was maintained at the C+95 position while for the C-terminal truncations, the N-terminus was maintained at the N+137 position (these constructs have a methionine residue appended to the N+136 N-cap residue). As can be seen, both proteins showed an apparent decrease in relative DNA binding affinity under the conditions of this assay when the protein was truncated on the N-terminus further than the N+134 position. Additionally, both proteins showed an apparent decrease in relative DNA binding affinity under the conditions of this assay when the C-terminus was truncated past amino acid C+54.

FIGS. 9A and 9B depict the DNA binding activity, as assayed by ELISA, of a series of N- and C-terminal truncations as described above. In FIG. 9A, the data for the NTF3-specific TALE DNA binding domain is shown, but in this case, when the N-terminal truncations were being tested, the C-terminus was maintained at the C+54 position. For the C-terminal truncations, the N-terminal amino acid was the N+134 position. In FIG. 9B, the data for the VEGF-specific TALE DNA binding domains is shown. As shown, the N- and C-terminal ends were maintained as described above for FIG. 9A.

FIG. 10 shows dissection of TALE functional domains involved for activity. The activities for reporter gene activation by indicated constructs as illustrated in Table 16 were investigated. The results indicate that (i) the N-terminal 152 amino acids and C-terminal 183 amino acids are not required for robust function in this assay; and (ii) the sequence flanking the tandem TALE repeats, including R0 region and the leucine rich domain, restore the functional activity in cells in this assay. Deletion of either N-terminal sequence preceding the first TALE repeat or C-terminal sequences following the last repeat abolishes functional activity in this assay. R13V-d145C has a C+133 C-cap, R13V-d182C has a C+95 C-cap, R13V-dC has a C+22 C-cap, nR13V-dN has a N+8 N-cap, nR13V-d223N has an N+52 N-cap and nR13V-d240 has an N+34 N-cap.

FIGS. 11A and 11B, depict nuclease activity of TALE13 linked to two copies of the FokI domain in K562 cells. FIG. 11A depicts a schematic of a single stranded annealing based reporter assay (SSA) for detecting the nuclease activity in mammalian cells. The reporter construct (SSA-R13) in this assay contained the TALE13 target, sandwiched by the N-terminal (GF) and C-terminal part (FP) of the GFP coding sequence. The plasmid SSA-R13 by itself cannot drive the GFP expression, but the cleavage of the R13 target promotes homologous recombination between the N-terminal (GF) and C-terminal (FP) part of the GFP to form a functional GFP. Thus, the nuclease activity of TALEN protein was assessed by analyzing the percentage of the GFP positive cells. FIG. 11B demonstrates nuclease activity by a TALEN protein. The GFP positive cells generated from SSA-R13 reporter construct increased significantly using a TALEN (R13d182C-scFokI; C+95 C-cap), compared to a control experiment lacking the nuclease plasmid (mock). R13d182C-scFokI is the same as R13V-d182C described above except that two copies of FokI domain, linked by 12 copies of GGGGS (SEQ ID NO: 124) sequences between the FokI domains, is used to replace the VP16 activation domain.

FIG. 12 depicts an ethidium bromide gel showing nuclease activity of the TALE-13 effector domain-FokI cleavage half-domain fusions in vitro. The columns show data for four TALE domain nuclease cleavage proteins: the nuclease fusion with a N+137, C+28 configuration using either the L2 or L8 linker (see Example 7); the nuclease fusion with the N+137, C+39 configuration, using the L2 linker; and the N+137, C+63 fusion with the L2 linker. The gap spacings between the two target sites are shown beneath the wells where the number indicates the number of by between the targets. “S” indicates a single target site for only one half of the pair. “PmlI” indicates cleavage with a standard restriction enzyme and blank indicates the results when the experiment was carried out without the nuclease encoding plasmid.

FIG. 13 is a graph depicting the DNA cleavage obtained by the indicated TALE13-FokI cleavage half domain fusions. “Dimer Gap” indicates the number of by between the two target sites, and “Percent DNA Cleavage” indicates how much DNA was cleaved in the reaction. The results indicate that virtually 100 percent DNA cleavage is achievable in these reaction conditions with the three of the four nucleases tested.

FIG. 14 depicts an ethidium bromide-stained gel showing nuclease activity of the TALE domain-FokI half cleavage domain fusions. In this experiment, the N-terminus was varied while the C-terminus was maintained with the C+63 configuration. The Pml1 and Blank controls are the same as for FIG. 12. The N-terminal truncations tested in this experiment were N+137, N+134, N+130 and N+119. The different DNA target sites are indicated as in FIG. 12 except that the label is above the cognate lane rather than below it. Activity of the nucleases is diminished when the N-terminus is shorter than approximately +134 to +137. The amount of DNA loaded in each lane for the 5 bp gap and 8 bp gap targets was uneven so it is difficult to determine if the lower bands in these lanes represent DNA cleavage products or background bands due to inefficient PCR at the inverted repeats.

FIGS. 15A and 15B, depict TALEN activity in K562 cells. FIG. 15A (SEQ ID NOS 342 and 452, respectively, in order of appearance) depicts the target sequence used in the reporter plasmid for the NTF3 targeting TALE pairs which also includes binding sites for a pair of CCR5-specific ZFNs (8267/8196). FIG. 15B is a graph depicting the results of the SSA nuclease assay where (−)NT3 R18 C28L8 (light gray bars; C+28 C-cap, L8 linker) depicts data observed when only one member of the NTF3-specific pair was present while (+)NT3 R18 C28L8 (dark gray bars) depicts the results when both members of the pair were present. “8267EL8196KK” indicates the results using the CCR5-specific ZFN pair.

FIG. 16 depicts the results of a Cel-I Surveyor™ mismatch assay (Transgenomics, “Cel-I assay”) on cells treated with various pairs of NTF3-targeting TALENs. The samples, numbered 1-30 are as described in the text. (+) denotes addition of the Cel-I enzyme, (−) denotes the assay without any added enzyme. A band of approximately 226 bp is apparent in most of the samples, indicating a mismatch induced by cleavage of the endogenous NTF3 target by the nuclease, followed by non-homologous end joining which introduces areas of mismatch with the wild type sequence. “gfp” indicates the control where cells were transfected with a GFP encoding plasmid only. The percent NHEJ activity quantitated on the gel is indicated in each sample containing the Cel-I enzyme. The gel demonstrates that the pairs induced targeted locus disruption at up to 8.66% of total alleles in some samples at this endogenous locus in a mammalian cell.

FIGS. 17A through 17C, depict the activity of NTF3-specific TALENs in K562 cells. FIG. 17A shows the SELEX specificity data for the engineered TALEN protein designated NT-R which is the engineered partner made for the NT-L TALEN fusion. The expected bases (SEQ ID NO: 549) and corresponding RVDs are shown above the plot. The +63 C-terminal flanking region was used for this SELEX experiment. FIG. 17B shows a gel of the results of a Cel-I assay using four NTF3-specific TALEN pairs in K562 cells where the culture conditions were either at 30° C. or 37° C. As can be seen from the data presented, the most active pair demonstrated gene modification levels of 3% at 37° C. and 9% under cold-shock conditions (30° C.) (Doyon et al. (2010) Nat Methods 8(1):74-9. Epub 2010 Dec. 5 and U.S. Publication No. 2011-0129898). 84 amplicons from the PCR pool from the cold-shock study were then sequenced, and seven mutated alleles were identified, which are shown in FIG. 17C (SEQ ID NO:343-350). As can be seen, small indels are observed.

FIGS. 18A and 18B, depict the sequencing results observed following endogenous cleavage of the NTF3 locus in K562 cells using TALENs. FIG. 18A depicts the chromosomal sequence (SEQ ID NO:139-140) and the boxes delineate the binding sites for the two TALENs. FIG. 18B depicts a compilation of sequencing results of the NTF3 locus from cells treated with the different NTF3 TALEN pairs described in Example 8 aligned with the wild-type (“wt”) sequence (SEQ ID NO:141-175).

FIG. 19 depicts the results of a targeted integration event at an endogenous gene via a DSB induced by the NTF3-specific TALENs. Oligonucleotides for capture in the DSB were synthesized to contain overhangs corresponding to all possible sequences within the space between the TALEN binding sites. PCR was done using a set of primers that primed off of the inserted oligonucleotide and a region outside the putative cut site. Eight (8) different pairs of NTF3-specific TALENs were tested wherein the pairs are labeled A-H. The legend shows a portion of the gel demonstrating how the lanes are read.

FIGS. 20A through 20D, show capture of an oligonucleotide duplex at an endogenous chromosomal locus mediated by NHEJ following a DSB induced at that locus by a TALEN pair. FIG. 20A shows part of the NTF3 target locus (top duplex, SEQ ID NOS 351 and 550, respectively, in order of appearance) and one of the oligonucleotide duplexes used for this study (bottom duplex, SEQ ID NOS 352 and 551, respectively, in order of appearance). Binding sites for NT-L+28 and NT-R+63 are underlined in the top sequence. The cleavage overhang that will most efficiently capture the duplex (5′ CTGG) is also highlighted. FIG. 20B shows part of the NTF3 target locus (top duplex, SEQ ID NOS 353 and 552, respectively, in order of appearance) and the second oligonucleotide duplex used for this study (bottom sequences, SEQ ID NOS 354 and 553, respectively, in order of appearance). Binding sites for NT-L+28 and NT-R+63 are underlined in the top sequence. The cleavage overhang that will most efficiently capture this second duplex (5′ TGGT) is also shown. FIG. 20C (SEQ ID NO:355-357) shows results following expression of NT-L+28 and NT-R+63 in K562 cells in the presence of the oligonucleotide duplex shown in FIG. 20A. Junctions between successfully integrated duplex and genomic DNA were then amplified using one primer that anneals within the duplex and one primer that anneals to the native NTF3 locus. The resulting amplicons were cloned and sequenced. The “expected” sequence at top indicates the sequence that would result from a perfect ligation of oligonucleotide duplex to the cleaved locus. The box highlights the location of the duplex overhang in the junction sequences. The bottom two lines provide junction sequences obtained from this study. As shown, eleven junction sequences resulted from perfect ligation of duplex to the cleavage overhang, while one junction sequence exhibited a short deletion (12 bp) consistent with resection prior to repair by NHEJ. FIG. 20D (SEQ ID NO:358-362) shows results from experiments as shown in FIG. 20C except that the oligonucleotide duplex shown in FIG. 20B was used, which has a 4 bp overhang that is shifted by one base relative to the duplex shown in FIG. 20A. The lowest four lines provide junction sequences obtained from this study. As shown, four distinct sequences were identified, which each exhibit short deletions consistent with resection prior to NHEJ-mediated repair.

FIG. 21 depicts several of the potential secondary DNA structures predicted to form in the natural TALE repeat domain during PCR amplification that can disrupt efficient amplification of the template. Analysis of the DNA sequence of the TALE-repeat protein was done using Mfold (M. Zuker Nucleic Acids Res. 31(13):3406-15, (2003)). 800 base pairs of the nucleic acid sequence were analyzed starting at the 5′ end of the nucleic acid encoding the first full TALE repeat sequence. The sequence analyzed contained approximately 7.5 repeats. Analysis revealed several very stable secondary structures. FIG. 21 discloses SEQ ID NO: 131.

FIG. 22 depicts pictoral results of in silico analysis of 1963 TALE repeats from Xanthomonas bacteria displaying the conserved amino acids at each position in the 34 amino acid repeat unit (SEQ ID NO:461). Letter size is inversely related to observed diversity at any given position: larger letters indicate less tolerance of diversity while smaller letters indicate the alternate amino acids that can be observed at a given location. Different shades of color represent different chemical classes of the amino acids. In this sample of 1963 TALE repeats, the most frequency RVDs were: 28.8% HD; 20.6% NI, 15.1% NN; 13.2% NG; 8.5% NS; 5.5% HG; and 5.5% NG* (where the asterisk indicates the RVD was observed in a 33-residue TALE repeat instead of the more typical 34-residue repeat). 15 other RVD sequences were observed in this sample, but these all had frequencies below 1%.

FIG. 23 depicts a schematic of the method used to tandemly link PCR amplicons of selected TALE repeat modules and ligate them into a vector backbone to create the desired TALE fusion protein. Specific primers are listed in Example 11. Also depicted is the vector backbone into which the assembled TALE fusion is cloned. The fusion partner domain is a FokI nuclease catalytic domain to allow production of one member of a TALEN pair.

FIGS. 24A and 24B, depict the use of TALENs to drive homology-based transfer of a short segment of heterology encoding a RFLP into the endogenous CCR5 locus. FIG. 24A shows a schematic for the assay, and depicts the location of the PCR primers used and the Bgl I site. FIG. 24B depicts a gel showing insertion of a 46 bp donor sequence into a DSB introduced by a CCR5-specific TALEN pair. The donor sequence contains a unique BglI restriction site, so upon PCR amplification of the target site and then digestion of the PCR product with BglI, sequences that have been cleaved by the TALEN pair and have had insertion of the 46 bp donor sequence will have two BglI cleavage products, as indicated in the Figure.

FIGS. 25A and 25B, are graphs depicting the cleavage efficacy of TALENs as compared to target gap spacings. FIG. 25A depicts the activity of a panel of CCR5-specific TALEN pair with a +28/+28 pairing (C+28 C-cap on both TALENs) while FIG. 25B depicts the activity of a panel CCR5-specific TALEN pair comprising a +63/+63 pairing (C+63 C-cap on both TALENs). As can be seen, the activity of the +28/+28 pair is more tightly constrained to a 12 or 13 bp gap spacing between the two target sequences while the +63/+63 pair exhibits activity across a gap spacing range of 12-23 bp.

FIG. 26 is a graph depicting the endogenous activity of a CCR5-specific TALEN pair with different length C-cap sequences, or stated another way, different sequences linking the array of full TALE repeats to the nuclease domain. C terminal truncations were made across the C-terminal sequence to yield C-caps from C−2 to C+278. These constructs were tested for TALEN activity in K562 cells against an endogenous target with an 18 bp gap spacing where the cells were incubated at either 37° C. (light squares) or cold shock conditions (30° C., dark diamonds). The activity was highly dependent on the identity of the sequence used to connect the array of full TALE repeats with the FokI cleavage domain. Note that our C-cap notation does not include C+0 so the C−1 C-cap value was plotted at X=0 and C−2 was plotted as X=−1. C+5, C+28, etc. were plotted as X=5, X=28, etc. Peak activity was observed for a C+63 C-cap sequence.

FIG. 27 depicts the specificity of an exemplary TALEN chosen for RVD analysis. The TALEN was designed to bind to the 11 base target sequence 5′-TTGACAATCCT-3′ (SEQ ID NO:178). Shown are the DNA binding results determine by ELISA analysis when this target is altered at position 6, such that the identity of the target at positions 5-7 is either CAA (designed target), CGA, TCG or TTG.

FIG. 28 is a graphical display of the ELISA affinities measured for all the RVDs tested. The data are shown in a 20×20 grid where the first amino acid of the RVD (position 12) is indicated on the vertical left of the grid and the second amino acid of the RVD (position 13) is indicated horizontally above the grid. The size of the letters A, C, G, and T in each grid is scaled based on the square root of the normalized ELISA signal for the CAA site, CCA site, and CGA site and CTA site respectively. Many RVDs have improved DNA binding properties with respect to the naturally occurring HD, NI, NG, NS, NN, IG, HG, and NK RVDs. The four RVDs that are the most frequently found in nature (HD, NG, NI, and NN) are boxed for reference. For these four RVDs, the preferred base by ELISA matched expected preferred base.

FIG. 29 are gels depicting the results of measurements of activity of TALENs in which the C-terminal half repeat has been altered at the RVD to allow interaction with nucleotide bases other than T. Shown TALEN activities as determined by Cel-I assay as described above. Arrow heads indicate bands that are a result of Cel-I cleavage at indels. Lane assignments are as listed in Example 16, Table 32. These results demonstrate that TALEN C-terminal half repeats can be engineered to bind to each nucleotide base as desired.

FIG. 30 are gels depicting the measurement of TALEN activity using TALENs that have TALE repeat units comprising either fully atypical RVDs (Fully Substituted), repeat domains where all the repeat units of one type or specificity have been substituted (e.g. all repeat units with RVDs that specify ‘T’ etc.) with atypical RVDs (Type Substitutions), or TALENs where only one repeat unit with the array has been substituted with an atypical RVD-comprising repeat unit (Singly Substituted). Activity assays were carried out either at 37 degrees or under cold shock conditions (30 degrees), and quantitation of any measurable NHEJ activity is indicated on the lanes.

FIG. 31 is a series of gels depicting the presence of NHEJ events in rat pups born following TALEN treatment of rat embryos. Genomic DNA was isolated from the pups and PCR was performed on the region surrounding the nuclease target site. The product was then examined for NHEJ induced mismatches using the T7 endonuclease. The arrow indicates the band that is produced from the presence of a mismatch. 7 of 66 pups examined (11%) were positive for an NHEJ event.

DETAILED DESCRIPTION OF THE INVENTION Introduction

The present application demonstrates that TALE-repeat domains can be engineered to recognize a desired endogenous DNA sequence and that fusing functional domains to such engineered TALE-repeat domains can be used to modify the functional state, or the actual genomic DNA sequence of an endogenous cellular locus, including a gene, that is present in its native chromatin environment. The present invention thus provides TALE-fusion DNA binding proteins that have been engineered to specifically recognize, with high efficacy, endogenous cellular loci including genes. As a result, the TALE-fusions of the invention can be used to regulate endogenous gene expression, both through activation and repression of endogenous gene transcription. The TALE-fusions can also be linked to other regulatory or functional domains, for example nucleases, transposases or methylases, to modify endogenous chromosomal sequences.

The methods and compositions described herein allow for novel human and mammalian therapeutic applications, e.g., treatment of genetic diseases, cancer, fungal, protozoal, bacterial, and viral infection, ischemia, vascular disease, arthritis, immunological disorders, etc., as well as providing for functional genomics assays, and generating engineered cell lines for research and drug screening, and means for developing plants with altered phenotypes, including but not limited to, increased disease resistance, and altering fruit ripening characteristics, sugar and oil composition, yield, and color.

As described herein, two or more TALE-fusions can be administered to any cell, recognizing either the same target endogenous cellular gene, or different target endogenous cellular genes.

In another embodiment, the TALE-fusion protein is linked to at least one or more regulatory domains, described below. Non-limiting examples of regulatory or functional domains include transcription factor repressor or activator domains such as KRAB and VP16, co-repressor and co-activator domains, DNA methyl transferases, histone acetyltransferases, histone deacetylases, and DNA cleavage domains such as the cleavage domain from the endonuclease FokI.

Described herein are also compositions and methods including fusion proteins comprising one or more TALE-repeat units, an N-cap and, optionally, a C-cap fused to nuclease domains useful for genomic editing (e.g., cleaving of genes; alteration of genes, for example by cleavage followed by insertion (physical insertion or insertion via homology-directed repair) of an exogenous sequence and/or cleavage followed by NHEJ; partial or complete inactivation of one or more genes; generation of alleles with altered functional states of endogenous genes, insertion of regulatory elements; etc.) and alterations of the genome which are carried into the germline. Also disclosed are methods of making and using these compositions (reagents), for example to edit (alter) one or more genes in a target cell. Thus, the methods and compositions described herein provide highly efficient methods for targeted gene alteration (e.g., knock-in) and/or knockout (partial or complete) of one or more genes and/or for randomized mutation of the sequence of any target allele, and, therefore, allow for the generation of animal models of human diseases.

Also disclosed herein are compositions (C-caps) for linking a nuclease domain to a TALE repeat array that provide highly active nuclease function. In some embodiments the C-cap comprises peptide sequence from a native TALE C-terminal flanking sequence. In other embodiments, the C-cap comprises peptide sequence from a TALE repeat domain. In yet another embodiment the C-cap comprises non-TALE sequences. C-caps may also exhibit a chimeric structure, containing peptide sequences from native TALE C-terminal flanking sequence and/or TALE repeat domains and/or neither of these sources.

TALENs can also be engineered to allow the insertion of a donor of interest into a safe harbor locus such as AAVS1 (see co-owned US Patent Publication 20080299580) or CCR5 (see co-owned United States Patent Publication 20080159996). The donor can comprise a gene of interest or can encode an RNA of interest such as an shRNA, RNAi or miRNA.

The expression of engineered TALE-fusion proteins (e.g., transcriptional activators, transcriptional repressors and nucleases) can be also controlled by systems typified by the tet-regulated systems and the RU-486 system (see, e.g., Gossen & Bujard, Proc Natl Acad Sci 89:5547 (1992); Oligino et al., Gene Ther. 5:491-496 (1998); Wang et al., Gene Ther. 4:432-441 (1997); Neering et al, Blood 88:1147-1155 (1996); and Rendahl et al., Nat. Biotechnol. 16:757-761 (1998)). These impart small molecule control on the expression of the TALE-fusion activators and repressors and thus impart small molecule control on the target gene(s) of interest. This beneficial feature could be used in cell culture models, in gene therapy, and in transgenic animals and plants.

General

Practice of the methods, as well as preparation and use of the compositions disclosed herein employ, unless otherwise indicated, conventional techniques in molecular biology, biochemistry, chromatin structure and analysis, computational chemistry, cell culture, recombinant DNA and related fields as are within the skill of the art. These techniques are fully explained in the literature. See, for example, Sambrook et al. MOLECULAR CLONING: A LABORATORY MANUAL, Second edition, Cold Spring Harbor Laboratory Press, 1989 and Third edition, 2001; Ausubel et al., CURRENT PROTOCOLS IN MOLECULAR BIOLOGY, John Wiley & Sons, New York, 1987 and periodic updates; the series METHODS IN ENZYMOLOGY, Academic Press, San Diego; Wolfe, CHROMATIN STRUCTURE AND FUNCTION, Third edition, Academic Press, San Diego, 1998; METHODS IN ENZYMOLOGY, Vol. 304, “Chromatin” (P. M. Wassarman and A. P. Wolffe, eds.), Academic Press, San Diego, 1999; and METHODS IN MOLECULAR BIOLOGY, Vol. 119, “Chromatin Protocols” (P. B. Becker, ed.) Humana Press, Totowa, 1999.

Definitions

The terms “nucleic acid,” “polynucleotide,” and “oligonucleotide” are used interchangeably and refer to a deoxyribonucleotide or ribonucleotide polymer, in linear or circular conformation, and in either single- or double-stranded form. For the purposes of the present disclosure, these terms are not to be construed as limiting with respect to the length of a polymer. The terms can encompass known analogues of natural nucleotides, as well as nucleotides that are modified in the base, sugar and/or phosphate moieties (e.g., phosphorothioate backbones). In general, an analogue of a particular nucleotide has the same base-pairing specificity; i.e., an analogue of A will base-pair with T.

The terms “polypeptide,” “peptide” and “protein” are used interchangeably to refer to a polymer of amino acid residues. The term also applies to amino acid polymers in which one or more amino acids are chemical analogues or modified derivatives of a corresponding naturally-occurring amino acids.

“Binding” refers to a sequence-specific, non-covalent interaction between macromolecules (e.g., between a protein and a nucleic acid). Not all components of a binding interaction need be sequence-specific (e.g., contacts with phosphate residues in a DNA backbone), as long as the interaction as a whole is sequence-specific. Such interactions are generally characterized by a dissociation constant (K_(d)) of 10⁻⁶M or lower. “Affinity” refers to the strength of binding: increased binding affinity being correlated with a lower K_(d).

A “binding protein” is a protein that is able to bind non-covalently to another molecule. A binding protein can bind to, for example, a DNA molecule (a DNA-binding protein), an RNA molecule (an RNA-binding protein) and/or a protein molecule (a protein-binding protein). In the case of a protein-binding protein, it can bind to itself (to form homodimers, homotrimers, etc.) and/or it can bind to one or more molecules of a different protein or proteins. A binding protein can have more than one type of binding activity. For example, zinc-finger proteins have DNA-binding, RNA-binding and protein-binding activity.

A “TALE-repeat domain” (also “repeat array”) is a sequence that is involved in the binding of the TALE to its cognate target DNA sequence and that comprises one or more TALE “repeat units.” A single “repeat unit” (also referred to as a “repeat”) is typically 33-35 amino acids in length and exhibits at least some sequence homology with other TALE repeat sequences within a naturally occurring TALE protein. A TALE repeat unit as described herein is generally of the form (X)^(1 to 11)-(X^(RVD))₂-(X)₂₀₋₂₂ (SEQ ID NO:399) where X^(RVD) (positions 12 and 13) exhibit hypervariability in naturally occurring TALE proteins. Altering the identity of the amino acids at positions 12 and 13 can alter the preference for the identity of the DNA nucleotide (or pair of complementary nucleotides in double-stranded DNA) with which the repeat unit interacts. An “atypical” RVD is an RVD sequence (positions 12 and 13) that occurs infrequently or never in nature, for example, in less than 5% of naturally occurring TALE proteins, preferably in less than 2% of naturally occurring TALE proteins and even more preferably less than 1% of naturally occurring TALE proteins. An atypical RVD can be non-naturally occurring.

The terms “N-cap” polypeptide and “N-terminal sequence” are used to refer to an amino acid sequence (polypeptide) that flanks the N-terminal portion of the TALE repeat domain. The N-cap sequence can be of any length (including no amino acids), so long as the TALE-repeat domain(s) function to bind DNA. Thus, an N-cap sequence may be involved in supplying proper structural stabilization for the TALE repeat domain and/or nonspecific contacts with DNA. An N-cap sequence may be naturally occurring or non-naturally occurring, for example it may be derived from the N-terminal region of any full length TALE protein. The N-cap sequence is preferably a fragment (truncation) of a polypeptide found in full-length TALE proteins, for example any truncation of a N-terminal region flanking the TALE repeat domain in a naturally occurring TALE protein that is sufficient to support DNA-binding function of the TALE-repeat domain or provide support for TALE fusion protein activity. When each TALE-repeat unit comprises a typical RVD and/or when the C-cap comprises a full-length naturally occurring C-terminal region of a TALE protein, the N-cap sequence does not comprise a full-length N-terminal region of a naturally occurring TALE protein. Thus, as noted above, this sequence is not necessarily involved in DNA recognition, but may enhance efficient and specific function at endogenous target DNA or efficient activity of the TALE fusion protein. The portion of the N-cap sequence closest to the N-terminal portion of the TALE repeat domain may bear some homology to a TALE repeat unit and is referred to as the “R0 repeat.” Typically, the preferred nucleotide to the position immediately 5′ of the target site is thymidine (T). It may be that the R0 repeat portion of the N-cap prefers to interact with a T (or the A base-paired to the T in double-stranded DNA) adjacent to the target sequence specified by the TALE repeats. Shown below is one example of an R0 sequence:

(SEQ ID NO: 1) LDTGQLLKIAKRGGVTAVEAVHAWRNALTGAPLN

The term “C-cap” or “C-terminal region” refers to optionally present amino acid sequences (polypeptides) that may be flanking the C-terminal portion of the TALE repeat domain. The C-cap can also comprise any part of a terminal C-terminal TALE repeat, including 0 residues, truncations of a TALE repeat or a full TALE repeat. The first 20 residues of the C-terminal region are typically homologous to the first 20 residues of a TALE repeat unit and may contain an RVD sequence capable of specifying the preference of nucleotides 3′ of the DNA sequence specified by the TALE repeat domain. When present, this portion of the C-terminal region homologous to the first 20 residues of a TALE repeat is also referred to as the “half repeat.” The numbering scheme of residues in the C-terminal region reflects this typical partial homology where the number scheme starts at C−20, increments to C−19, C−18, C−17, C−16, C−15, C−14, C−13, C−12, C−11, C−10, C−9, C−8, C−7, C−6, C−5, C−4, C−3, C−2, C−1, increments to C+1, and then increments to C+2, C+3, etc. towards the C-terminus of the polypeptide. A C+28 C-cap refers to the sequence from residue C−20 to residue C+28 (inclusive) and thus has a length of 48 residues. The C-cap sequences may be naturally occurring (e.g., fragments of naturally occurring proteins) or non-naturally occurring (e.g., a fragment of a naturally occurring protein comprising one or more amino acid deletions, substitutions and/or additions), or any other natural or non-natural sequence with the ability to act as a C cap. The C-terminal region is not absolutely required for the DNA-binding function of the TALE repeat domain(s), but, in some embodiments, a C-cap may interact with DNA and also may enhance the activity of functional domains, for example in a fusion protein comprising a nuclease at the C-terminal to the TALE repeat domain.

A “zinc-finger DNA binding protein” (or binding domain) is a protein, or a domain within a larger protein, that binds DNA in a sequence-specific manner through one or more zinc-fingers, which are regions of amino acid sequence within the binding domain whose structure is stabilized through coordination of a zinc ion. The term zinc-finger DNA binding protein is often abbreviated as zinc-finger protein or ZFP.

A “selected” zinc-finger protein or protein comprising a TALE-repeat domain is a protein whose production results primarily from an empirical process such as phage display, interaction trap or hybrid selection. See e.g., U.S. Pat. No. 5,789,538; U.S. Pat. No. 5,925,523; U.S. Pat. No. 6,007,988; U.S. Pat. No. 6,013,453; U.S. Pat. No. 6,200,759; WO 95/19431; WO 96/06166; WO 98/53057; WO 98/54311; WO 00/27878; WO 01/60970 WO 01/88197 and WO 02/099084.

The term “sequence” refers to a nucleotide sequence of any length, which can be DNA or RNA; can be linear, circular or branched and can be either single-stranded or double stranded. The term “donor sequence” refers to a nucleotide sequence that is inserted into a genome. A donor sequence can be of any length, for example between 2 and 10,000 nucleotides in length (or any integer value therebetween or thereabove), preferably between about 100 and 1,000 nucleotides in length (or any integer therebetween), more preferably between about 200 and 500 nucleotides in length.

A “homologous, non-identical sequence” refers to a first sequence which shares a degree of sequence identity with a second sequence, but whose sequence is not identical to that of the second sequence. For example, a polynucleotide comprising the wild-type sequence of a mutant gene is homologous and non-identical to the sequence of the mutant gene. In certain embodiments, the degree of homology between the two sequences is sufficient to allow homologous recombination therebetween, utilizing normal cellular mechanisms. Two homologous non-identical sequences can be any length and their degree of non-homology can be as small as a single nucleotide (e.g., for correction of a genomic point mutation by targeted homologous recombination) or as large as 10 or more kilobases (e.g., for insertion of a gene at a predetermined ectopic site in a chromosome). Two polynucleotides comprising the homologous non-identical sequences need not be the same length. For example, an exogenous polynucleotide (i.e., donor polynucleotide) of between 20 and 10,000 nucleotides or nucleotide pairs can be used.

Techniques for determining nucleic acid and amino acid sequence identity are known in the art. Typically, such techniques include determining the nucleotide sequence of the mRNA for a gene and/or determining the amino acid sequence encoded thereby, and comparing these sequences to a second nucleotide or amino acid sequence. Genomic sequences can also be determined and compared in this fashion. In general, identity refers to an exact nucleotide-to-nucleotide or amino acid-to-amino acid correspondence of two polynucleotides or polypeptide sequences, respectively. Two or more sequences (polynucleotide or amino acid) can be compared by determining their percent identity. The percent identity of two sequences, whether nucleic acid or amino acid sequences, is the number of exact matches between two aligned sequences divided by the length of the shorter sequences and multiplied by 100.

Alternatively, the degree of sequence similarity between polynucleotides can be determined by hybridization of polynucleotides under conditions that allow formation of stable duplexes between homologous regions, followed by digestion with single-stranded-specific nuclease(s), and size determination of the digested fragments. Two nucleic acid, or two polypeptide sequences are substantially homologous to each other when the sequences exhibit at least about 70%-75%, preferably 80%-82%, more preferably 85%-90%, even more preferably 92%, still more preferably 95%, and most preferably 98% sequence identity over a defined length of the molecules, as determined using the methods above. As used herein, substantially homologous also refers to sequences showing complete identity to a specified DNA or polypeptide sequence. DNA sequences that are substantially homologous can be identified in a Southern hybridization experiment under, for example, stringent conditions, as defined for that particular system. Defining appropriate hybridization conditions is within the skill of the art. See, e.g., Sambrook et al., supra; Nucleic Acid Hybridization: A Practical Approach, editors B. D. Hames and S. J. Higgins, (1985) Oxford; Washington, D.C.; IRL Press).

“Recombination” refers to a process of exchange of genetic information between two polynucleotides. For the purposes of this disclosure, “homologous recombination (HR)” refers to the specialized form of such exchange that takes place, for example, during repair of double-strand breaks in cells via homology-directed repair mechanisms. This process requires nucleotide sequence homology, uses a “donor” molecule to template repair of a “target” molecule (i.e., the one that experienced the double-strand break), and is variously known as “non-crossover gene conversion” or “short tract gene conversion,” because it leads to the transfer of genetic information from the donor to the target. Without wishing to be bound by any particular theory, such transfer can involve mismatch correction of heteroduplex DNA that forms between the broken target and the donor, and/or “synthesis-dependent strand annealing,” in which the donor is used to resynthesize genetic information that will become part of the target, and/or related processes. Such specialized HR often results in an alteration of the sequence of the target molecule such that part or all of the sequence of the donor polynucleotide is incorporated into the target polynucleotide.

In the methods of the disclosure, one or more targeted nucleases as described herein create a double-stranded break in the target sequence (e.g., cellular chromatin) at a predetermined site, and a “donor” polynucleotide, having homology to the nucleotide sequence in the region of the break, can be introduced into the cell. The presence of the double-stranded break (DSB) has been shown to facilitate integration of the donor sequence. The donor sequence may be physically integrated or, alternatively, the donor polynucleotide is used as a template for repair of the break via homologous recombination, resulting in the introduction of all or part of the nucleotide sequence as in the donor into the cellular chromatin. Thus, a first sequence in cellular chromatin can be altered and, in certain embodiments, can be converted into a sequence present in a donor polynucleotide. Thus, the use of the terms “replace” or “replacement” can be understood to represent replacement of one nucleotide sequence by another, (i.e., replacement of a sequence in the informational sense), and does not necessarily require physical or chemical replacement of one polynucleotide by another. In some embodiments, two DSBs are introduced by the targeted nucleases described herein, resulting in the deletion of the DNA in between the DSBs. In some embodiments, the “donor” polynucleotides are inserted between these two DSBs.

Thus, in certain embodiments, portions of the donor sequence that are homologous to sequences in the region of interest exhibit between about 80 to 99% (or any integer therebetween) sequence identity to the genomic sequence that is replaced. In other embodiments, the homology between the donor and genomic sequence is higher than 99%, for example if only 1 nucleotide differs as between donor and genomic sequences of over 100 contiguous base pairs. In certain cases, a non-homologous portion of the donor sequence can contain sequences not present in the region of interest, such that new sequences are introduced into the region of interest. In these instances, the non-homologous sequence is generally flanked by sequences of 50-1,000 base pairs (or any integral value therebetween) or any number of base pairs greater than 1,000, that are homologous or identical to sequences in the region of interest. In other embodiments, the donor sequence is non-homologous to the first sequence, and is inserted into the genome by non-homologous recombination mechanisms.

In any of the methods described herein, additional TALE-fusion proteins fused to nuclease domains as well as additional pairs of TALE-(or zinc finger) nucleases can be used for additional double-stranded cleavage of additional target sites within the cell.

Any of the methods described herein can be used for partial or complete inactivation of one or more target sequences in a cell by targeted integration of donor sequence that disrupts expression of the gene(s) of interest. Cell lines with partially or completely inactivated genes are also provided.

Furthermore, the methods of targeted integration as described herein can also be used to integrate one or more exogenous sequences. The exogenous nucleic acid sequence can comprise, for example, one or more genes or cDNA molecules, or any type of coding or noncoding sequence, as well as one or more control elements (e.g., promoters). In addition, the exogenous nucleic acid sequence may produce one or more RNA molecules (e.g., small hairpin RNAs (shRNAs), inhibitory RNAs (RNAis), microRNAs (miRNAs), etc.).

“Cleavage” refers to the breakage of the covalent backbone of a DNA molecule. Cleavage can be initiated by a variety of methods including, but not limited to, enzymatic or chemical hydrolysis of a phosphodiester bond. Both single-stranded cleavage and double-stranded cleavage are possible, and double-stranded cleavage can occur as a result of two distinct single-stranded cleavage events. DNA cleavage can result in the production of either blunt ends or staggered ends. In certain embodiments, fusion polypeptides are used for targeted double-stranded DNA cleavage.

A “cleavage half-domain” is a polypeptide sequence which, in conjunction with a second polypeptide (either identical or different) forms a complex having cleavage activity (preferably double-strand cleavage activity). The terms “first and second cleavage half-domains;” “+ and − cleavage half-domains” and “right and left cleavage half-domains” are used interchangeably to refer to pairs of cleavage half-domains that dimerize.

An “engineered cleavage half-domain” is a cleavage half-domain that has been modified so as to form obligate heterodimers with another cleavage half-domain (e.g., another engineered cleavage half-domain). See, also, U.S. Patent Publication Nos. 2005/0064474; 2007/0218528 and 2008/0131962, incorporated herein by reference in their entireties.

“Chromatin” is the nucleoprotein structure comprising the cellular genome. Cellular chromatin comprises nucleic acid, primarily DNA, and protein, including histones and non-histone chromosomal proteins. The majority of eukaryotic cellular chromatin exists in the form of nucleosomes, wherein a nucleosome core comprises approximately 150 base pairs of DNA associated with an octamer comprising two each of histones H2A, H2B, H3 and H4; and linker DNA (of variable length depending on the organism) extends between nucleosome cores. A molecule of histone H1 is generally associated with the linker DNA. For the purposes of the present disclosure, the term “chromatin” is meant to encompass all types of cellular nucleoprotein, both prokaryotic and eukaryotic. Cellular chromatin includes both chromosomal and episomal chromatin.

A “chromosome,” is a chromatin complex comprising all or a portion of the genome of a cell. The genome of a cell is often characterized by its karyotype, which is the collection of all the chromosomes that comprise the genome of the cell. The genome of a cell can comprise one or more chromosomes.

An “episome” is a replicating nucleic acid, nucleoprotein complex or other structure comprising a nucleic acid that is not part of the chromosomal karyotype of a cell. Examples of episomes include plasmids and certain viral genomes.

A “target site” or “target sequence” is a nucleic acid sequence that defines a portion of a nucleic acid to which a binding molecule will bind, provided sufficient conditions for binding exist. For example, the sequence 5′-GAATTC-3′ is a target site for the Eco RI restriction endonuclease.

“Plant” cells include, but are not limited to, cells of monocotyledonous (monocots) or dicotyledonous (dicots) plants. Non-limiting examples of monocots include cereal plants such as maize, rice, barley, oats, wheat, sorghum, rye, sugarcane, pineapple, onion, banana, and coconut. Non-limiting examples of dicots include tobacco, tomato, sunflower, cotton, sugarbeet, potato, lettuce, melon, soybean, canola (rapeseed), and alfalfa. Plant cells may be from any part of the plant and/or from any stage of plant development.

An “exogenous” molecule is a molecule that is not normally present in a cell, but can be introduced into a cell by one or more genetic, biochemical or other methods. “Normal presence in the cell” is determined with respect to the particular developmental stage and environmental conditions of the cell. Thus, for example, a molecule that is present only during embryonic development of muscle is an exogenous molecule with respect to an adult muscle cell. Similarly, a molecule induced by heat shock is an exogenous molecule with respect to a non-heat-shocked cell. An exogenous molecule can comprise, for example, a functioning version of a malfunctioning endogenous molecule or a malfunctioning version of a normally-functioning endogenous molecule. An exogenous molecule can also be a molecule normally found in another species, for example, a human sequence introduced into an animal's genome.

An exogenous molecule can be, among other things, a small molecule, such as is generated by a combinatorial chemistry process, or a macromolecule such as a protein, nucleic acid, carbohydrate, lipid, glycoprotein, lipoprotein, polysaccharide, any modified derivative of the above molecules, or any complex comprising one or more of the above molecules. Nucleic acids include DNA and RNA, can be single- or double-stranded; can be linear, branched or circular; and can be of any length. Nucleic acids include those capable of forming duplexes, as well as triplex-forming nucleic acids. See, for example, U.S. Pat. Nos. 5,176,996 and 5,422,251. Proteins include, but are not limited to, DNA-binding proteins, transcription factors, chromatin remodeling factors, methylated DNA binding proteins, polymerases, methylases, demethylases, acetylases, deacetylases, kinases, phosphatases, integrases, recombinases, ligases, topoisomerases, gyrases and helicases.

An exogenous molecule can be the same type of molecule as an endogenous molecule, e.g., an exogenous protein or nucleic acid. For example, an exogenous nucleic acid can comprise an infecting viral genome, a plasmid or episome introduced into a cell, or a chromosome that is not normally present in the cell. Methods for the introduction of exogenous molecules into cells are known to those of skill in the art and include, but are not limited to, lipid-mediated transfer (i.e., liposomes, including neutral and cationic lipids), electroporation, direct injection, cell fusion, particle bombardment, calcium phosphate co-precipitation, DEAE-dextran-mediated transfer and viral vector-mediated transfer.

By contrast, an “endogenous” molecule is one that is normally present in a particular cell at a particular developmental stage under particular environmental conditions. For example, an endogenous nucleic acid can comprise a chromosome, the genome of a mitochondrion, chloroplast or other organelle, or a naturally-occurring episomal nucleic acid. Additional endogenous molecules can include proteins, for example, transcription factors and enzymes.

A “fusion” molecule is a molecule in which two or more subunit molecules are linked, preferably covalently. The subunit molecules can be the same chemical type of molecule, or can be different chemical types of molecules. Examples of the first type of fusion molecule include, but are not limited to, fusion proteins (for example, a fusion between a TALE-repeat domain and a cleavage domain) and fusion nucleic acids (for example, a nucleic acid encoding the fusion protein described supra). Examples of the second type of fusion molecule include, but are not limited to, a fusion between a triplex-forming nucleic acid and a polypeptide, and a fusion between a minor groove binder and a nucleic acid.

Expression of a fusion protein in a cell can result from delivery of the fusion protein to the cell or by delivery of a polynucleotide encoding the fusion protein to a cell, wherein the polynucleotide is transcribed, and the transcript is translated, to generate the fusion protein. Trans-splicing, polypeptide cleavage and polypeptide ligation can also be involved in expression of a protein in a cell. Methods for polynucleotide and polypeptide delivery to cells are presented elsewhere in this disclosure.

A “gene,” for the purposes of the present disclosure, includes a DNA region encoding a gene product (see infra), as well as all DNA regions which regulate the production of the gene product, whether or not such regulatory sequences are adjacent to coding and/or transcribed sequences. Accordingly, a gene includes, but is not necessarily limited to, promoter sequences, terminators, translational regulatory sequences such as ribosome binding sites and internal ribosome entry sites, enhancers, silencers, insulators, boundary elements, replication origins, matrix attachment sites and locus control regions.

“Gene expression” refers to the conversion of the information, contained in a gene, into a gene product. A gene product can be the direct transcriptional product of a gene (e.g., mRNA, tRNA, rRNA, antisense RNA, ribozyme, structural RNA, shRNA, RNAi, miRNA or any other type of RNA) or a protein produced by translation of a mRNA. Gene products also include RNAs which are modified, by processes such as capping, polyadenylation, methylation, and editing, and proteins modified by, for example, methylation, acetylation, phosphorylation, ubiquitination, ADP-ribosylation, myristilation, and glycosylation.

A “gap size” refers to the nucleotides between the two TALE targets sites on the nucleic acid target. Gaps can be any size, including but not limited to between 1 and 100 base pairs, or 5 and 30 base pairs, preferably between 10 and 25 base pairs, and more preferably between 12 and 21 base pairs. Thus, a preferable gap size may be 12, 13, 14, 15, 16, 17, 18, 19, 20, or 21 base pairs.

“Modulation” of gene expression refers to a change in the activity of a gene. Modulation of expression can include, but is not limited to, gene activation and gene repression. Genome editing (e.g., cleavage, alteration, inactivation, donor integration, random mutation) can be used to modulate expression. Gene inactivation refers to any reduction in gene expression as compared to a cell that does not include a modifier as described herein. Thus, gene inactivation may be partial or complete.

A “region of interest” is any region of cellular chromatin, such as, for example, a gene or a non-coding sequence within or adjacent to a gene, in which it is desirable to bind an exogenous molecule. Binding can be for the purposes of targeted DNA cleavage and/or targeted recombination. A region of interest can be present in a chromosome, an episome, an organellar genome (e.g., mitochondrial, chloroplast), or an infecting viral genome, for example. A region of interest can be within the coding region of a gene, within transcribed non-coding regions such as, for example, leader sequences, trailer sequences or introns, or within non-transcribed regions, either upstream or downstream of the coding region. A region of interest can be as small as a single nucleotide pair or up to 2,000 nucleotide pairs in length, or any integral value of nucleotide pairs.

The terms “operative linkage” and “operatively linked” (or “operably linked”) are used interchangeably with reference to a juxtaposition of two or more components (such as sequence elements), in which the components are arranged such that both components function normally and allow the possibility that at least one of the components can mediate a function that is exerted upon at least one of the other components. By way of illustration, a transcriptional regulatory sequence, such as a promoter, is operatively linked to a coding sequence if the transcriptional regulatory sequence controls the level of transcription of the coding sequence in response to the presence or absence of one or more transcriptional regulatory factors. A transcriptional regulatory sequence is generally operatively linked in cis with a coding sequence, but need not be directly adjacent to it. For example, an enhancer is a transcriptional regulatory sequence that is operatively linked to a coding sequence, even though they are not contiguous.

With respect to fusion polypeptides, the term “operatively linked” can refer to the fact that each of the components performs the same function in linkage to the other component as it would if it were not so linked. For example, with respect to a fusion polypeptide in which a TALE-repeat domain is fused to a cleavage domain, the TALE-repeat domain and the cleavage domain are in operative linkage if, in the fusion polypeptide, the TALE-repeat domain portion is able to bind its target site and/or its binding site, while the cleavage domain is able to cleave DNA in the vicinity of the target site.

A “functional fragment” of a protein, polypeptide or nucleic acid is a protein, polypeptide or nucleic acid whose sequence is not identical to the full-length protein, polypeptide or nucleic acid, yet retains the same or has enhanced function as compared to the full-length protein, polypeptide or nucleic acid. Additionally, a functional fragment may have lesser function than the full-length protein, polypeptide or nucleic acid, but still have adequate function as defined by the user. A functional fragment can possess more, fewer, or the same number of residues as the corresponding native molecule, and/or can contain one or more amino acid or nucleotide substitutions. Methods for determining the function of a nucleic acid (e.g., coding function, ability to hybridize to another nucleic acid) are well-known in the art. Similarly, methods for determining protein function are well-known. For example, the DNA-binding function of a polypeptide can be determined, for example, by filter-binding, electrophoretic mobility-shift, or immunoprecipitation assays. DNA cleavage can be assayed by gel electrophoresis. See Ausubel et al., supra. The ability of a protein to interact with another protein can be determined, for example, by co-immunoprecipitation, two-hybrid assays or complementation, both genetic and biochemical. See, for example, Fields et al. (1989) Nature 340:245-246; U.S. Pat. No. 5,585,245 and PCT WO 98/44350.

TALE-repeat domains can be “engineered” to bind to a predetermined nucleotide sequence, for example via engineering (altering one or more amino acids) of the hypervariable diresidue region, for example positions 12 and/or 13 of a repeat unit within a TALE protein. In some embodiments, the amino acids at positions 4, 11, and 32 may be engineered. In other embodiments, atypical RVDs may be selected for use in an engineered TALE protein, enabling specification of a wider range of non-natural target sites. For example, a NK RVD may be selected for use in recognizing a G nucleotide in the target sequence. In other embodiments, amino acids in the repeat unit may be altered to change the characteristics (i.e. stability or secondary structure) of the repeat unit. Therefore, engineered TALE proteins are proteins that are non-naturally occurring. In some embodiments, the genes encoding TALE repeat domains are engineered at the DNA level such that the codons specifying the TALE repeat amino acids are altered, but the specified amino acids are not (e.g., via known techniques of codon optimization). Non-limiting examples of engineered TALE proteins are those obtained by design and/or selection. A designed TALE protein is a protein not occurring in nature whose design/composition results principally from rational criteria. Rational criteria for design include application of substitution rules and computerized algorithms for processing information in a database storing information of existing TALE designs and binding data. A “selected” TALE-repeat domain is a non-naturally occurring or atypical domain whose production results primarily from an empirical process such as phage display, interaction trap or hybrid selection.

A “multimerization domain” is a domain incorporated at the amino, carboxy or amino and carboxy terminal regions of a TALE-fusion protein. These domains allow for multimerization of multiple TALE-fusion protein units. Examples of multimerization domains include leucine zippers. Multimerization domains may also be regulated by small molecules wherein the multimerization domain assumes a proper conformation to allow for interaction with another multimerization domain only in the presence of a small molecule or external ligand. In this way, exogenous ligands can be used to regulate the activity of these domains.

The target sites useful in the above methods can be subject to evaluation by other criteria or can be used directly for design or selection (if needed) and production of a TALE-fusion protein specific for such a site. A further criterion for evaluating potential target sites is their proximity to particular regions within a gene. Target sites can be selected that do not necessarily include or overlap segments of demonstrable biological significance with target genes, such as regulatory sequences. Other criteria for further evaluating target segments include the prior availability of TALE-fusion proteins binding to such segments or related segments, and/or ease of designing new TALE-fusion proteins to bind a given target segment.

After a target segment has been selected, a TALE-fusion protein that binds to the segment can be provided by a variety of approaches. Once a TALE-fusion protein has been selected, designed, or otherwise provided to a given target segment, the TALE-fusion protein or the DNA encoding it are synthesized. Exemplary methods for synthesizing and expressing DNA encoding TALE-repeat domain-containing proteins are described below. The TALE-fusion protein or a polynucleotide encoding it can then be used for modulation of expression, or analysis of the target gene containing the target site to which the TALE-fusion protein binds.

TALE DNA Binding Domains

The polypeptides described herein comprise one or more (e.g., 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 or even more) TALE-repeat units. TALE DNA binding domains, comprising multiple TALE-repeat units, have been studied to determine the sequences responsible for specificity. Within one organism, the TALE repeats typically are highly conserved (except for the RVD) but may not be well conserved across different species.

A TALE-repeat unit as found in the polypeptides described herein is generally of the form: X¹-X²-X³-X⁴-X⁵-X⁶-X⁷-X⁸-X⁹-X¹⁰-X¹¹-(X^(RVD))₂-(X)₂₀₋₂₂ (SEQ ID NO:399), where X is any amino acid and X^(RVD) (positions 12 and 13) involved in DNA binding. Non-limiting exemplary embodiments of such domains include: embodiments in which X¹ comprises a leucine (L), or methionine (M) residue; embodiments in which X¹⁰ comprises an alanine (A) residue or a valine (V) residue; embodiments in which (X)₂₀₋₂₂ comprises the sequence (Gly or Ser)-(X)₁₉₋₂₁ (SEQ ID NO:400); embodiments in which (X)₂₀₋₂₂ comprises the sequence (X)₃₋₄-(Ala or Thr)-(X)₁₆₋₁₇ (SEQ ID NO:401); embodiments in which (X)₂₀₋₂₂ comprises the sequence (X)₄₋₅-(Leu or Val)-(X)₁₅₋₁₆ (SEQ ID NO:402); and combinations of any of the above embodiments (e.g., comprises a leucine (L) or methionine (M) residue and X¹⁰ comprises an alanine (A) residue; X¹ comprises L or M and (X)₂₀₋₂₂ comprises the sequence Gly/Ser-(X)₁₉₋₂₁; (X)₂₀₋₂₂ comprises the sequence Gly/Ser-(X)₂₋₃-Ala/Thr-(X)₁₆₋₁₇; X¹⁰ comprises an alanine (A) or valine (V) residue and (X)₂₀₋₂₂ comprises the sequence Gly/Ser-(X)₁₉₋₂₁, etc.).

The TALE-repeat units of the compositions and methods described herein may be derived from any suitable TALE-protein. Non-limiting examples of TALE proteins include TALE proteins derived from Ralstonia spp. or Xanthamonas spp. Thus, in some embodiments, the DNA-binding domain comprises one or more one or more naturally occurring and/or engineered TALE-repeat units derived from the plant pathogen Xanthomonas (see Boch et al, (2009) Science 326: 1509-1512 and Moscou and Bogdanove, (2009) Science 326: 1501). In other embodiments, the DNA-binding domain comprises one or more naturally occurring and/or engineered TALE-repeat units derived from the plant pathogen Ralstonia solanacearum, or other TALE DNA binding domain from the TALE protein family. The TALE DNA binding domains as described herein (comprising at least one TALE repeat unit) can include (i) one or more TALE repeat units not found in nature; (ii) one or more naturally occurring TALE repeat units; (iii) one or more TALE repeat units with atypical RVDs; and combinations of (i), (ii) and/or (iii). In some embodiments, a TALE DNA binding domain of the invention consists of completely non-naturally occurring or atypical repeat units. Furthermore, in polypeptides as described herein comprising two or more TALE-repeat units, the TALE-repeat units (naturally occurring or engineered) may be derived from the same species or alternatively, may be derived from different species.

Table 1 shows an alignment of exemplary repeat units within two TALE proteins. Each TALE repeat is shown on a separate line with the columns indicating the type of repeat, position of the start of that repeat, the name of the repeat, the residues at the hypervariable positions, and the entire repeat sequence.

The DNA-binding polypeptides comprising TALE-repeat domains as described herein may also include additional TALE polypeptide sequences, for example N-terminal (N-cap) sequences and, optionally, C-terminal (C-cap) sequences flanking the repeat domains. N-cap sequences may be naturally or non-naturally occurring sequences of any length sufficient to support the function (e.g., DNA-binding, cleavage, activation, etc.) of the DNA-binding polypeptide and fusion proteins comprising these TALE-repeat domain-containing DNA-binding polypeptides. In certain embodiments, the protein comprises an N-cap sequence comprising a fragment (truncation) of a region of a TALE protein N-terminal to the repeat domain (e.g., an N-cap sequence comprising at least 130 to 140 residues (e.g., 131, 132, 133, 134, 135, 136, 137, 138, 139 or 140 residues) of a TALE polypeptide N-terminal of the repeat domain). In other embodiments, the TALE-repeat domain polypeptides as described herein the protein comprises a C-cap sequence comprising a fragment (truncated) region of a TALE protein C-terminal to the repeat domain (e.g., an C-cap sequence comprising C−20 to C+28, C−20 to C+55, or C−20 to C+63). In certain embodiments, the C-cap sequence comprises a half-repeat (C−20 to C−1). The TALE DNA-binding polypeptides as described herein may include N-cap, C-cap sequences or both N-cap and C-cap sequences.

Artificial TALE proteins and TALE fusion proteins can be produced to bind to a novel sequence using natural or engineered TALE repeat units (see Boch et al, ibid and Morbitzer et al, (2010) Proc. Natl. Acad. Sci. USA 107(50):21617-21622). See, also e.g., WO 2010/079430. When this novel target sequence was inserted upstream of a reporter gene in plant cells, the researchers were able to demonstrate activation of the reporter gene. Artificial TALE fusions comprising the FokI cleavage domain can also cleave DNA in living cells (see Christin et al, ibid, Li et at (2011a) and (2011b) ibid, Cernak et at (2011) Nucl. Acid. Res. epub doi:10.1093/nar/gcr218.

An engineered TALE protein and TALE fusion protein can have a novel binding specificity, compared to a naturally-occurring TALE protein. Engineering methods include, but are not limited to, rational design and various types of selection. Rational design includes, for example, using databases comprising nucleotide sequences for modules for single or multiple TALE repeats. Exemplary selection methods, including phage display and two-hybrid systems, are disclosed in U.S. Pat. Nos. 5,789,538; 5,925,523; 6,007,988; 6,013,453; 6,410,248; 6,140,466; 6,200,759; and 6,242,568; as well as WO 98/37186; WO 98/53057; WO 00/27878; WO 01/88197 and GB 2,338,237. In naturally occurring TALE proteins, only a limited repertoire of potential dipeptide motifs are typically employed. Thus, as described herein, TALE related domains containing all possible mono- and di-peptide sequences have been constructed and assembled into candidate TALE proteins. Thus, in certain embodiments, one or more TALE-repeat units of the DNA-binding protein comprise atypical RVDs.

Additionally, in naturally occurring TALE proteins of the same species, the repeat units often show little variability within the framework sequence (i.e. the residue(s) not involved in direct DNA contact (non-RVD residues). This lack of variability may be due to a number of factors including evolutionary relationships between individual TALE repeat units and protein folding requirements between adjacent repeats. Between differing phytopathogenic bacterial species however the framework sequences can vary. For example, the TALE repeat sequences in the Xanthomonas campestris pv vesicatoria, the protein AvrBs3 has less than 40% homology with brg11 and hpx17 repeat units from Ralstonia solanacearum (see Heuer et al (2007) Appl Environ Micro 73 (13): 4379-4384). The TALE repeat may be under stringent functional selection in each bacterium's natural environment, e.g., from the sequence of the genes in the host plant that the TALE regulates. Thus, as described herein, variants in the TALE framework (e.g., within the TALE repeat unit or sequences outside the repeat units such as N-cap and C-cap sequences) may be introduced by targeted or random mutagenesis by various methods know in the art, and the resultant TALE fusion proteins screened for optimal activity.

Multi TALE repeat modules may also be useful not only for assembling the DNA binding domains (comprising at least one TALE repeat unit) as described above, but also may be useful for the assembly of mini-TALE multimers (i.e. trimers, tetramers, pentamers etc.), wherein spanning linkers that also functioned as capping regions between the mini-TALE DNA binding domains would allow for base skipping and may result in higher DNA binding specificity. The use of linked mini-TALE DNA binding domains would relax the requirement for strict functional modularity at the level of individual TALE repeats and allows for the development of more complex and/or specific DNA recognition schemes wherein amino acids from adjacent motifs within a given module might be free to interact with each other for cooperative recognition of a desired DNA target sequence. Mini-TALE DNA binding domains could be linked and expressed using a suitable selection system (i.e. phage display) with randomized dipeptide motifs (or any other identified key positions) and selected based on their nucleic acid binding characteristics. Alternatively, multi-TALE repeat modules may be used to create an archive of repeat modules to allow for rapid construction of any specific desired TALE-fusion protein.

Selection of target sites and methods for design and construction of fusion proteins (and polynucleotides encoding same) are known to those of skill in the art and described in detail in U.S. Patent Application Publication Nos. 20050064474 and 20060188987, incorporated by reference in their entireties herein.

Artificial fusion proteins linking TALE DNA binding domains to zinc finger DNA binding domains may also be produced. These fusions may also be further linked to a desired functional domain.

In addition, as disclosed in these and other references, TALE DNA binding domains and/or zinc finger domains may be linked together using any suitable linker sequences, including for example, linkers of 5 or more amino acids in length (e.g., TGEKP (SEQ ID NO:48), TGGQRP (SEQ ID NO:49), TGQKP (SEQ ID NO:50), and/or TGSQKP (SEQ ID NO:51)), although it is likely that sequences that can function as capping sequence (N-cap and C-cap sequences) would be required at the interface between the TALE repeat domain and the linker. Thus, when linkers are used, linkers of five or more amino acids can be used in conjunction with the cap sequences to join the TALE DNA binding domains to a desired fusion partner domain. See, also, U.S. Pat. Nos. 6,479,626; 6,903,185; and 7,153,949 for exemplary linker sequences 6 or more amino acids in length. In addition, linkers between the TALE repeat domains and the fused functional protein domains can be constructed to be either flexible or positionally constrained to allow for the most efficient genomic modification. Linkers of varying lengths and compositions may be tested.

Fusion Proteins

Fusion proteins comprising DNA-binding proteins (e.g., TALE-fusion proteins) as described herein and a heterologous regulatory or functional domain (or functional fragment thereof) are also provided. Common domains include, e.g., transcription factor domains (activators, repressors, co-activators, co-repressors), nuclease domains, silencer domains, oncogene domains (e.g., myc, jun, fos, myb, max, mad, rel, ets, bcl, myb, mos family members etc.); DNA repair enzymes and their associated factors and modifiers; DNA rearrangement enzymes and their associated factors and modifiers; chromatin associated proteins and their modifiers (e.g. kinases, acetylases and deacetylases); and DNA modifying enzymes (e.g., methyltransferases, topoisomerases, helicases, ligases, kinases, phosphatases, polymerases, endonucleases), DNA targeting enzymes such as transposons, integrases, recombinases and resolvases and their associated factors and modifiers, nuclear hormone receptors, nucleases (cleavage domains or half-domains) and ligand binding domains. Other fusion proteins may include reporter or selection markers. Examples of reporter domains include GFP, GUS and the like. Reporters with specific utility in plant cells include GUS.

Suitable domains for achieving activation include the HSV VP16 activation domain (see, e.g., Hagmann et al., J. Virol. 71, 5952-5962 (1997)) nuclear hormone receptors (see, e.g., Torchia et al., Curr. Opin. Cell. Biol. 10:373-383 (1998)); the p65 subunit of nuclear factor kappa B (Bitko & Barik, J. Virol. 72:5610-5618 (1998) and Doyle & Hunt, Neuroreport 8:2937-2942 (1997)); Liu et al., Cancer Gene Ther. 5:3-28 (1998)), or artificial chimeric functional domains such as VP64 (Beerli et al., (1998) Proc. Natl. Acad. Sci. USA 95:14623-33), and degron (Molinari et al., (1999) EMBO J. 18, 6439-6447). Additional exemplary activation domains include, Oct 1, Oct-2A, Sp1, AP-2, and CTF1 (Seipel et al., EMBO J. 11, 4961-4968 (1992) as well as p300, CBP, PCAF, SRC1 PvALF, AtHD2A and ERF-2. See, for example, Robyr et al. (2000) Mol. Endocrinol. 14:329-347; Collingwood et al. (1999) J Mol. Endocrinol. 23:255-275; Leo et al. (2000) Gene 245:1-11; Manteuffel-Cymborowska (1999) Acta Biochim. Pol. 46:77-89; McKenna et al. (1999) J. Steroid Biochem. Mol. Biol. 69:3-12; Malik et al. (2000) Trends Biochem. Sci. 25:277-283; and Lemon et al. (1999) Curr. Opin. Genet. Dev. 9:499-504. Additional exemplary activation domains include, but are not limited to, OsGAI, HALF-1, C1, AP1, ARF-5, -6, -7, and -8, CPRF1, CPRF4, MYC-RP/GP, and TRAB1. See, for example, Ogawa et al. (2000) Gene 245:21-29; Okanami et al. (1996) Genes Cells 1:87-99; Goff et al. (1991) Genes Dev. 5:298-309; Cho et al. (1999) Plant Mol. Biol. 40:419-429; Ulmason et al. (1999) Proc. Natl. Acad. Sci. USA 96:5844-5849; Sprenger-Haussels et al. (2000) Plant 22:1-8; Gong et al. (1999) Plant Mot. Biol. 41:33-44; and Hobo et al. (1999) Proc. Natl. Acad. Sci. USA 96:15,348-15,353.

It will be clear to those of skill in the art that, in the formation of a fusion protein (or a nucleic acid encoding same) between a DNA-binding domain as described herein and a functional domain, either an activation domain or a molecule that interacts with an activation domain is suitable as a functional domain. Essentially any molecule capable of recruiting an activating complex and/or activating activity (such as, for example, histone acetylation) to the target gene is useful as an activating domain of a fusion protein. Insulator domains, localization domains, and chromatin remodeling proteins such as ISWI-containing domains and/or methyl binding domain proteins suitable for use as functional domains in fusion molecules are described, for example, in co-owned U.S. Patent Applications 2002/0115215 and 2003/0082552 and in co-owned WO 02/44376.

Exemplary repression domains include, but are not limited to, KRAB A/B, KOX, TGF-beta-inducible early gene (TIEG), v-erbA, SID, MBD2, MBD3, members of the DNMT family (e.g., DNMT1, DNMT3A, DNMT3B), Rb, and MeCP2. See, for example, Bird et al. (1999) Cell 99:451-454; Tyler et al. (1999) Cell 99:443-446; Knoepfler et al. (1999) Cell 99:447-450; and Robertson et al. (2000) Nature Genet. 25:338-342. Additional exemplary repression domains include, but are not limited to, ROM2 and AtHD2A. See, for example, Chem et al. (1996) Plant Cell 8:305-321; and Wu et al. (2000) Plant J. 22:19-27.

In certain embodiments, the target site bound by the TALE-fusion protein is present in an accessible region of cellular chromatin. Accessible regions can be determined as described, for example, in co-owned International Publication WO 01/83732. If the target site is not present in an accessible region of cellular chromatin, one or more accessible regions can be generated as described in co-owned WO 01/83793. In additional embodiments, the DNA-binding domain of a fusion molecule is capable of binding to cellular chromatin regardless of whether its target site is in an accessible region or not. For example, such DNA-binding domains are capable of binding to linker DNA and/or nucleosomal DNA. Examples of this type of “pioneer” DNA binding domain are found in certain steroid receptor and in hepatocyte nuclear factor 3 (HNF3). Cordingley et al. (1987) Cell 48:261-270; Pina et al. (1990) Cell 60:719-731; and Cirillo et al. (1998) EMBO J. 17:244-254.

The fusion molecule may be formulated with a pharmaceutically acceptable carrier, as is known to those of skill in the art. See, for example, Remington's Pharmaceutical Sciences, 17th ed., 1985; and co-owned WO 00/42219.

The functional component/domain of a fusion molecule can be selected from any of a variety of different components capable of influencing transcription of a gene once the fusion molecule binds to a target sequence via its DNA binding domain. Hence, the functional component can include, but is not limited to, various transcription factor domains, such as activators, repressors, co-activators, co-repressors, and silencers.

Additional exemplary functional domains are disclosed, for example, in co-owned U.S. Pat. No. 6,534,261 and US Patent Application Publication No. 2002/0160940.

Functional domains that are regulated by exogenous small molecules or ligands may also be selected. For example, RheoSwitch® technology may be employed wherein a functional domain only assumes its active conformation in the presence of the external RheoChem™ ligand (see for example US 20090136465). Thus, the TALE-fusion protein may be operably linked to the regulatable functional domain wherein the resultant activity of the TALE-fusion protein is controlled by the external ligand.

In certain embodiments, the TALE DNA-binding proteins, or fragments thereof, are used as nucleases via fusion (N- and/or C-terminal to the TALE-repeat domain, N-cap and/or C-cap sequences) of a TALE DNA-binding domain to at least one nuclease (cleavage domain, cleavage half-domain). The cleavage domain portion of the fusion proteins disclosed herein can be obtained from any endonuclease or exonuclease. Exemplary endonucleases from which a cleavage domain can be derived include, but are not limited to, restriction endonucleases and homing endonucleases. See, for example, 2002-2003 Catalogue, New England Biolabs, Beverly, Mass.; and Belfort et al. (1997) Nucleic Acids Res. 25:3379-3388. Additional enzymes which cleave DNA are known (e.g., 51 Nuclease; mung bean nuclease; pancreatic DNase I; micrococcal nuclease; yeast HO endonuclease; see also Linn et al. (eds.) Nucleases, Cold Spring Harbor Laboratory Press, 1993). One or more of these enzymes (or functional fragments thereof) can be used as a source of cleavage domains and cleavage half-domains.

Similarly, a cleavage half-domain can be derived from any nuclease or portion thereof, as set forth above, that requires dimerization for cleavage activity. In general, two fusion proteins are required for cleavage if the fusion proteins comprise cleavage half-domains. Alternatively, a single protein comprising two cleavage half-domains can be used. The two cleavage half-domains can be derived from the same endonuclease (or functional fragments thereof), or each cleavage half-domain can be derived from a different endonuclease (or functional fragments thereof). In addition, the target sites for the two fusion proteins are preferably disposed, with respect to each other, such that binding of the two fusion proteins to their respective target sites places the cleavage half-domains in a spatial orientation to each other that allows the cleavage half-domains to form a functional cleavage domain, e.g., by dimerizing. Thus, in certain embodiments, the near edges of the target sites are separated by 5-8 nucleotides or by 15-18 nucleotides. However, any integral number of nucleotides or nucleotide pairs can intervene between two target sites (e.g., from 2 to 50 nucleotide pairs or more). In general, the site of cleavage lies between the target sites.

Restriction endonucleases (restriction enzymes) are present in many species and are capable of sequence-specific binding to DNA (at a recognition site), and cleaving DNA at or near the site of binding. Certain restriction enzymes (e.g., Type IIS) cleave DNA at sites removed from the recognition site and have separable binding and cleavage domains. For example, the Type IIS enzyme Fok I catalyzes double-stranded cleavage of DNA, at 9 nucleotides from its recognition site on one strand and 13 nucleotides from its recognition site on the other. See, for example, U.S. Pat. Nos. 5,356,802; 5,436,150 and 5,487,994; as well as Li et al. (1992) Proc. Natl. Acad. Sci. USA 89:4275-4279; Li et al. (1993) Proc. Natl. Acad. Sci. USA 90:2764-2768; Kim et al. (1994a) Proc. Natl. Acad. Sci. USA 91:883-887; Kim et al. (1994b) J. Biol. Chem. 269:31,978-31,982. Thus, in one embodiment, fusion proteins comprise the cleavage domain (or cleavage half-domain) from at least one Type IIS restriction enzyme and one or more TALE DNA-binding domains, which may or may not be engineered.

Exemplary Type IIS restriction enzymes, whose cleavage domains are separable from the binding domain, include Fok I and BfiI (see Zaremba et al, (2004) J Mol Biol. 336(1):81-92). Fok enzyme is active as a dimer (see Bitinaite et al. (1998) Proc. Natl. Acad. Sci. USA 95: 10,570-10,575). For targeted double-stranded cleavage and/or targeted replacement of cellular sequences using TALE repeat domain-Fok I fusions (or variants thereof further comprising a C-cap and an N-cap), two fusion proteins, each comprising a FokI cleavage half-domain, can be used to reconstitute a catalytically active cleavage domain. Alternatively, a single polypeptide molecule containing a TALE-repeat domain and two Fok I cleavage half-domains can also be used. Another preferred Type IIS restriction enzyme is BfiI (see Zaremba et al, (2004) J Mol Biol. 336(1):81-92). The cleavage domain of this enzyme may be separated from its DNA binding domain and operably linked to a TALE DNA binding domain to create a TALEN.

A cleavage domain or cleavage half-domain can be any portion of a protein that retains cleavage activity, or that retains the ability to multimerize (e.g., dimerize) to form a functional cleavage domain.

Exemplary Type IIS restriction enzymes are described in International Publication WO 07/014275, incorporated herein in its entirety. Additional restriction enzymes also contain separable binding and cleavage domains, and these are contemplated by the present disclosure. See, for example, Roberts et al. (2003) Nucleic Acids Res. 31:418-420.

To enhance cleavage specificity, in certain embodiments, the cleavage domain comprises one or more engineered cleavage half-domain (also referred to as dimerization domain mutants) that minimize or prevent homodimerization, as described, for example, in U.S. Patent Publication Nos. 20050064474; 20060188987, 20080131962, 20090311787; 20090305346; 20110014616, and 20110201055, the disclosures of all of which are incorporated by reference in their entireties herein. Amino acid residues at positions 446, 447, 479, 483, 484, 486, 487, 490, 491, 496, 498, 499, 500, 531, 534, 537, and 538 of Fok I are all targets for influencing dimerization of the Fok I cleavage half-domains.

Exemplary engineered cleavage half-domains of Fok I that form obligate heterodimers include a pair in which a first cleavage half-domain includes mutations at amino acid residues at positions 490 and 538 of Fok I and a second cleavage half-domain includes mutations at amino acid residues 486 and 499.

Additional engineered cleavage half-domains of Fok I form an obligate heterodimers can also be used in the fusion proteins described herein. The first cleavage half-domain includes mutations at amino acid residues at positions 490 and 538 of Fok I and the second cleavage half-domain includes mutations at amino acid residues 486 and 499.

Thus, in one embodiment, a mutation at 490 replaces Glu (E) with Lys (K); the mutation at 538 replaces Iso (I) with Lys (K); the mutation at 486 replaced Gln (Q) with Glu (E); and the mutation at position 499 replaces Iso (I) with Lys (K). Specifically, the engineered cleavage half-domains described herein were prepared by mutating positions 490 (E→K) and 538 (I→K) in one cleavage half-domain to produce an engineered cleavage half-domain designated “E490K:I538K” and by mutating positions 486 (Q→E) and 499 (I→L) in another cleavage half-domain to produce an engineered cleavage half-domain designated “Q486E:I499L”. The engineered cleavage half-domains described herein are obligate heterodimer mutants in which aberrant cleavage is minimized or abolished. See, e.g., Example 1 of U.S. Patent Publication No. 2008/0131962, the disclosure of which is incorporated by reference in its entirety for all purposes.

The engineered cleavage half-domains described herein are obligate heterodimer mutants in which aberrant cleavage is minimized or abolished. See, e.g., Example 1 of WO 07/139898. In certain embodiments, the engineered cleavage half-domain comprises mutations at positions 486, 499 and 496 (numbered relative to wild-type FokI), for instance mutations that replace the wild type Gln (Q) residue at position 486 with a Glu (E) residue, the wild type Iso (I) residue at position 499 with a Leu (L) residue and the wild-type Asn (N) residue at position 496 with an Asp (D) or Glu (E) residue (also referred to as a “ELD” and “ELE” domains, respectively). In other embodiments, the engineered cleavage half-domain comprises mutations at positions 490, 538 and 537 (numbered relative to wild-type FokI), for instance mutations that replace the wild type Glu (E) residue at position 490 with a Lys (K) residue, the wild type Iso (I) residue at position 538 with a Lys (K) residue, and the wild-type His (H) residue at position 537 with a Lys (K) residue or a Arg (R) residue (also referred to as “KKK” and “KKR” domains, respectively). In other embodiments, the engineered cleavage half-domain comprises mutations at positions 490 and 537 (numbered relative to wild-type FokI), for instance mutations that replace the wild type Glu (E) residue at position 490 with a Lys (K) residue and the wild-type His (H) residue at position 537 with a Lys (K) residue or a Arg (R) residue (also referred to as “KIK” and “KIR” domains, respectively). (See U.S. Patent Publication 20110201055). In addition, the FokI nuclease domain variants including mutations known as “Sharkey” or “Sharkey′ (Sharkey prime)” mutations may be used (see Guo et al, (2010) J. Mol. Biol. doi:10.1016/j.jmb 0.2010.04.060).

Engineered cleavage half-domains described herein can be prepared using any suitable method, for example, by site-directed mutagenesis of wild-type cleavage half-domains (Fok I) as described in U.S. Patent Publication Nos. 20050064474, 20070134796; 20080131962.

TALE-fusion polypeptides and nucleic acids can be made using routine techniques in the field of recombinant genetics. Basic texts disclosing the general methods of use in this invention include Sambrook et al., Molecular Cloning, A Laboratory Manual (2nd ed. 1989); Kriegler, Gene Transfer and Expression: A Laboratory Manual (1990); and Current Protocols in Molecular Biology (Ausubel et al., eds., 1994)). In addition, essentially any nucleic acid can be custom ordered from any of a variety of commercial sources. Similarly, peptides and antibodies can be custom ordered from any of a variety of commercial sources.

Two alternative methods are typically used to create the coding sequences required to express newly designed DNA-binding peptides. One protocol is a PCR-based assembly procedure that utilizes overlapping oligonucleotides. These oligonucleotides contain substitutions primarily, but not limited to, positions 12 and 13 on the repeated domains making them specific for each of the different DNA-binding domains. Additionally, amino acid substitutions may be made at positions 4, 11 and 32. Amino acid substitutions may also be made at positions 2, 3, 4, 21, 23, 24, 25, 27, 30, 31, 33, 34 and/or 35 within one repeat unit. In some embodiments, the repeat unit contains a substitution in one position, and in others, the repeat unit contains from 2 to 18 amino acid substitutions. In some embodiments, the nucleotide sequence of the repeat units may be altered without altering the amino acid sequence.

Any suitable method of protein purification known to those of skill in the art can be used to purify TALE-fusion proteins of the invention (see Ausubel, supra, Sambrook, supra). In addition, any suitable host can be used, e.g., bacterial cells, insect cells, yeast cells, mammalian cells, and the like.

Thus, fusion molecules are constructed by methods of cloning and biochemical conjugation that are well known to those of skill in the art. Fusion molecules comprise a DNA-binding domain and a functional domain (e.g., a transcriptional activation or repression domain). Fusion molecules also optionally comprise nuclear localization signals (such as, for example, that from the SV40 medium T-antigen) and epitope tags (such as, for example, FLAG and hemagglutinin). Fusion proteins (and nucleic acids encoding them) are designed such that the translational reading frame is preserved among the components of the fusion. The fusion proteins as described herein may include one or more functional domains at the N- and/or C-terminus of the DNA-binding polypeptides as described herein.

Fusions between a polypeptide component of a functional domain (or a functional fragment thereof) on the one hand, and a non-protein DNA-binding domain (e.g., antibiotic, intercalator, minor groove binder, nucleic acid) on the other, are constructed by methods of biochemical conjugation known to those of skill in the art. See, for example, the Pierce Chemical Company (Rockford, Ill.) Catalogue. Methods and compositions for making fusions between a minor groove binder and a polypeptide have been described. Mapp et al. (2000) Proc. Natl. Acad. Sci. USA 97:3930-3935.

Additional Methods for Targeted Cleavage

Any nuclease having a target site in any desired gene(s) can be used in the methods disclosed herein. For example, homing endonucleases and meganucleases have very long recognition sequences, some of which are likely to be present, on a statistical basis, once in a human-sized genome. Any such nuclease having a target site in a desired gene can be used instead of, or in addition to, a TALE-repeat domain nuclease fusion, including for example, a zinc finger nuclease and/or a meganuclease, for targeted cleavage.

In certain embodiments, the nuclease is a meganuclease (homing endonuclease). Naturally-occurring meganucleases recognize 15-40 base-pair cleavage sites and are commonly grouped into four families: the LAGLIDADG family (“LAGLIDADG” disclosed as SEQ ID NO: 125), the GIY-YIG family, the His-Cyst box family and the HNH family. Exemplary homing endonucleases include I-SceI, I-CeuI, PI-PspI, PI-Sce, I-SceIV, I-CsmI, I-PanI, I-SceII, I-PpoI, I-SceIII, I-CreI, I-TevI, I-TevII and I-TevIII. Their recognition sequences are known. See also U.S. Pat. No. 5,420,032; U.S. Pat. No. 6,833,252; Belfort et al. (1997) Nucleic Acids Res. 25:3379-3388; Dujon et al. (1989) Gene 82:115-118; Perler et al. (1994) Nucleic Acids Res. 22, 1125-1127; Jasin (1996) Trends Genet. 12:224-228; Gimble et al. (1996) J. Mol. Biol. 263:163-180; Argast et al. (1998) J. Mol. Biol. 280:345-353 and the New England Biolabs catalogue.

DNA-binding domains from naturally-occurring meganucleases, primarily from the LAGLIDADG family (“LAGLIDADG” disclosed as SEQ ID NO: 125), have been used to promote site-specific genome modification in plants, yeast, Drosophila, mammalian cells and mice, but this approach has been limited to the modification of either homologous genes that conserve the meganuclease recognition sequence (Monet et al. (1999), Biochem. Biophysics. Res. Common. 255: 88-93) or to pre-engineered genomes into which a recognition sequence has been introduced (Route et al. (1994), Mol. Cell. Biol. 14: 8096-106; Chilton et al. (2003), Plant Physiology. 133: 956-65; Puchta et al. (1996), Proc. Natl. Acad. Sci. USA 93: 5055-60; Rong et al. (2002), Genes Dev. 16: 1568-81; Gouble et al. (2006), J. Gene Med. 8(5):616-622). Accordingly, attempts have been made to engineer meganucleases to exhibit novel binding specificity at medically or biotechnologically relevant sites (Porteus et al. (2005), Nat. Biotechnol. 23: 967-73; Sussman et al. (2004), J. Mol. Biol. 342: 31-41; Epinat et al. (2003), Nucleic Acids Res. 31: 2952-62; Chevalier et al. (2002) Molec. Cell 10:895-905; Epinat et al. (2003) Nucleic Acids Res. 31:2952-2962; Ashworth et al. (2006) Nature 441:656-659; Paques et al. (2007) Current Gene Therapy 7:49-66; U.S. Patent Publication Nos. 20070117128; 20060206949; 20060153826; 20060078552; and 20040002092).

Delivery

The TALE-fusion proteins, polynucleotides encoding same and compositions comprising the proteins and/or polynucleotides described herein may be delivered to a target cell by any suitable means, including, for example, by injection of mRNA encoding the TAL-fusion protein. See, Hammerschmidt et al. (1999) Methods Cell Biol. 59:87-115.

Methods of delivering proteins comprising engineered transcription factors are described, for example, in U.S. Pat. Nos. 6,453,242; 6,503,717; 6,534,261; 6,599,692; 6,607,882; 6,689,558; 6,824,978; 6,933,113; 6,979,539; 7,013,219; and 7,163,824, the disclosures of all of which are incorporated by reference herein in their entireties.

TALE-protein fusions as described herein may also be delivered using vectors containing sequences encoding one or more of the TALE-protein fusions. Any vector systems may be used including, but not limited to, plasmid vectors, retroviral vectors, lentiviral vectors, adenovirus vectors, poxvirus vectors; herpesvirus vectors and adeno-associated virus vectors, etc. See, also, U.S. Pat. Nos. 6,534,261; 6,607,882; 6,824,978; 6,933,113; 6,979,539; 7,013,219; and 7,163,824, incorporated by reference herein in their entireties. Furthermore, it will be apparent that any of these vectors may comprise one or more TALE-protein fusions encoding sequences. Thus, when one or more TALE-protein fusions (e.g., a pair of TALENs) are introduced into the cell, the TALE-protein fusions may be carried on the same vector or on different vectors. When multiple vectors are used, each vector may comprise a sequence encoding one or multiple TALE-protein fusions.

Conventional viral and non-viral based gene transfer methods can be used to introduce nucleic acids encoding engineered TALE-protein fusions in cells (e.g. mammalian cells) whole organisms or target tissues. Such methods can also be used to administer nucleic acids encoding TALE-protein fusions to cells in vitro. In certain embodiments, nucleic acids encoding TALE protein fusions are administered for in vivo or ex vivo uses. Non-viral vector delivery systems include DNA plasmids, naked nucleic acid, and nucleic acid complexed with a delivery vehicle such as a liposome or poloxamer. Viral vector delivery systems include DNA and RNA viruses, which have either episomal or integrated genomes after delivery to the cell. For a review of in vivo delivery of engineered DNA-binding proteins and fusion proteins comprising these binding proteins, see, e.g., Rebar (2004) Expert Opinion Invest. Drugs 13(7):829-839; Rossi et al. (2007) Nature Biotech. 25(12):1444-1454 as well as general gene delivery references such as Anderson, Science 256:808-813 (1992); Nabel & Felgner, TIBTECH 11:211-217 (1993); Mitani & Caskey, TIBTECH 11:162-166 (1993); Dillon, TIBTECH 11:167-175 (1993); Miller, Nature 357:455-460 (1992); Van Brunt, Biotechnology 6(10):1149-1154 (1988); Vigne, Restorative Neurology and Neuroscience 8:35-36 (1995); Kremer & Perricaudet, British Medical Bulletin 51(1):31-44 (1995); Haddada et al., in Current Topics in Microbiology and Immunology Doerfler and Böhm (eds.) (1995); and Yu et al., Gene Therapy 1:13-26 (1994).

Non-viral vector delivery systems include electroporation, lipofection, microinjection, biolistics, virosomes, liposomes, immunoliposomes, polycation or lipid:nucleic acid conjugates, naked DNA, artificial virions, and agent-enhanced uptake of DNA. Sonoporation using, e.g., the Sonitron 2000 system (Rich-Mar) can also be used for delivery of nucleic acids. Viral vector delivery systems include DNA and RNA viruses, which have either episomal or integrated genomes after delivery to the cell. Additional exemplary nucleic acid delivery systems include those provided by Amaxa Biosystems (Cologne, Germany), Maxcyte, Inc. (Rockville, Md.), BTX Molecular Delivery Systems (Holliston, Mass.) and Copernicus Therapeutics Inc, (see for example U.S. Pat. No. 6,008,336). Lipofection is described in e.g., U.S. Pat. No. 5,049,386, U.S. Pat. No. 4,946,787; and U.S. Pat. No. 4,897,355) and lipofection reagents are sold commercially (e.g., Transfectam™ and Lipofectin™). Cationic and neutral lipids that are suitable for efficient receptor-recognition lipofection of polynucleotides include those of Felgner, WO 91/17424, WO 91/16024. Delivery can be to cells (ex vivo administration) or target tissues (in vivo administration).

The preparation of lipid:nucleic acid complexes, including targeted liposomes such as immunolipid complexes, is well known to one of skill in the art (see, e.g., Crystal, Science 270:404-410 (1995); Blaese et al., Cancer Gene Ther. 2:291-297 (1995); Behr et al., Bioconjugate Chem. 5:382-389 (1994); Remy et al., Bioconjugate Chem. 5:647-654 (1994); Gao et al., Gene Therapy 2:710-722 (1995); Ahmad et al., Cancer Res. 52:4817-4820 (1992); U.S. Pat. Nos. 4,186,183, 4,217,344, 4,235,871, 4,261,975, 4,485,054, 4,501,728, 4,774,085, 4,837,028, and 4,946,787).

Additional methods of delivery include the use of packaging the nucleic acids to be delivered into EnGeneIC delivery vehicles (EDVs). These EDVs are specifically delivered to target tissues using bispecific antibodies where one arm of the antibody has specificity for the target tissue and the other has specificity for the EDV. The antibody brings the EDVs to the target cell surface and then the EDV is brought into the cell by endocytosis. Once in the cell, the contents are released (see MacDiarmid et at (2009) Nature Biotechnology vol 27(7) p. 643).

Suitable cells include but are not limited to eukaryotic and prokaryotic cells and/or cell lines. Non-limiting examples of such cells or cell lines generated from such cells include COS, CHO (e.g., CHO-S, CHO-K1, CHO-DG44, CHO-DUXB11, CHO-DUKX, CHOK1SV), VERO, MDCK, WI38, V79, B14AF28-G3, BHK, HaK, NS0, SP2/0-Ag14, HeLa, HEK293 (e.g., HEK293-F, HEK293-H, HEK293-T), and perC6 cells as well as insect cells such as Spodoptera fugiperda (Sf), or fungal cells such as Saccharomyces, Pichia and Schizosaccharomyces. In certain embodiments, the cell line is a CHO-K1, MDCK or HEK293 cell line. Additionally, primary cells may be isolated and used ex vivo for reintroduction into the subject to be treated following treatment with the TALE-fusions. Suitable primary cells include peripheral blood mononuclear cells (PBMC), and other blood cell subsets such as, but not limited to, CD4+ T cells or CD8+ T cells. Suitable cells also include stem cells such as, by way of example, embryonic stem cells, induced pluripotent stem cells, hematopoietic stem cells, neuronal stem cells, mesenchymal stem cells, muscle stem cells and skin stem cells.

Stem cells that have been modified may also be used in some embodiments. For example, stem cells that have been made resistant to apoptosis may be used as therapeutic compositions where the stem cells also contain the TALE-fusion proteins of the invention. Resistance to apoptosis may come about, for example, by knocking out BAX and/or BAK using BAX- or BAK-specific TALENs in the stem cells, or those that are disrupted in a caspase, again using caspase-6 specific TALENs for example.

Methods for introduction of DNA into hematopoietic stem cells are disclosed, for example, in U.S. Pat. No. 5,928,638. Vectors useful for introduction of transgenes into hematopoietic stem cells, e.g., CD34⁺ cells, include adenovirus Type 35.

Vectors suitable for introduction of polynucleotides as described herein include described herein include non-integrating lentivirus vectors (IDLV). See, for example, Ory et al. (1996) Proc. Natl. Acad. Sci. USA 93:11382-11388; Dull et al. (1998) J. Virol. 72:8463-8471; Zuffery et al. (1998) J. Virol. 72:9873-9880; Follenzi et al. (2000) Nature Genetics 25:217-222; U.S. Patent Publication No 2009/054985. As noted above, the disclosed methods and compositions can be used in any type of cell. Progeny, variants and derivatives of animal cells can also be used.

DNA constructs may be introduced into (e.g., into the genome of) a desired plant host by a variety of conventional techniques. For reviews of such techniques see, for example, Weissbach & Weissbach Methods for Plant Molecular Biology (1988, Academic Press, N.Y.) Section VIII, pp. 421-463; and Grierson & Corey, Plant Molecular Biology (1988, 2d Ed.), Blackie, London, Ch. 7-9.

For example, the DNA construct may be introduced directly into the genomic DNA of the plant cell using techniques such as electroporation and microinjection of plant cell protoplasts, or the DNA constructs can be introduced directly to plant tissue using biolistic methods, such as DNA particle bombardment (see, e.g., Klein et at (1987) Nature 327:70-73). Alternatively, the DNA constructs may be combined with suitable T-DNA flanking regions and introduced into a conventional Agrobacterium tumefaciens host vector. Agrobacterium tumefaciens-mediated transformation techniques, including disarming and use of binary vectors, are well described in the scientific literature. See, for example Horsch et at (1984) Science 233:496-498, and Fraley et at (1983) Proc. Nat'l. Acad. Sci. USA 80:4803.

In addition, gene transfer may be achieved using non-Agrobacterium bacteria or viruses such as Rhizobium sp. NGR234, Sinorhizoboium meliloti, Mesorhizobium loti, potato virus X, cauliflower mosaic virus and cassava vein mosaic virus and/or tobacco mosaic virus, See, e.g., Chung et al. (2006) Trends Plant Sci. 11(1): 1-4.

The virulence functions of the Agrobacterium tumefaciens host will direct the insertion of the construct and adjacent marker into the plant cell DNA when the cell is infected by the bacteria using binary T DNA vector (Bevan (1984) Nuc. Acid Res. 12:8711-8721) or the co-cultivation procedure (Horsch et at (1985) Science 227:1229-1231). Generally, the Agrobacterium transformation system is used to engineer dicotyledonous plants (Bevan et at (1982) Ann. Rev. Genet 16:357-384; Rogers et at (1986) Methods Enzymol. 118:627-641). The Agrobacterium transformation system may also be used to transform, as well as transfer, DNA to monocotyledonous plants and plant cells. See U.S. Pat. No. 5,591,616; Hernalsteen et at (1984) EMBO J 3:3039-3041; Hooykass-Van Slogteren et at (1984) Nature 311:763-764; Grimsley et al (1987) Nature 325:1677-179; Boulton et al (1989) Plant Mol. Biol. 12:31-40; and Gould et al (1991) Plant Physiol. 95:426-434.

Alternative gene transfer and transformation methods include, but are not limited to, protoplast transformation through calcium-, polyethylene glycol (PEG)- or electroporation-mediated uptake of naked DNA (see Paszkowski et al. (1984) EMBO J 3:2717-2722, Potrykus et al. (1985) Molec. Gen. Genet. 199:169-177; Fromm et al. (1985) Proc. Nat. Acad. Sci. USA 82:5824-5828; and Shimamoto (1989) Nature 338:274-276) and electroporation of plant tissues (D'Halluin et al. (1992) Plant Cell 4:1495-1505). Additional methods for plant cell transformation include microinjection, silicon carbide mediated DNA uptake (Kaeppler et al. (1990) Plant Cell Reporter 9:415-418), and microprojectile bombardment (see Klein et al. (1988) Proc. Nat. Acad. Sci. USA 85:4305-4309; and Gordon-Kamm et al. (1990) Plant Cell 2:603-618).

Eukaryotic (e.g., yeast, plant, fungal, piscine and mammalian cells such as feline, canine, murine, bovine, ovine, and porcine) cells can be used. Cells from organisms containing one or more homozygous KO loci as described herein or other genetic modifications can also be used.

(1977) J. Gen. Virol. 36:59), and myeloma cells like SP2 or NS0 (see, e.g., Galfre and Milstein (1981) Meth. Enzymol. 73(B):3 46). Peripheral blood mononucleocytes (PBMCs) or T-cells can also be used, as can embryonic and adult stem cells. For example, stem cells that can be used include embryonic stem cells (ES), induced pluripotent stem cells (iPSC), mesenchymal stem cells, hematopoietic stem cells, liver stem cells, skin stem cells and neuronal stem cells.

Exemplary target plants and plant cells include, but are not limited to, those monocotyledonous and dicotyledonous plants, such as crops including grain crops (e.g., wheat, maize, rice, millet, barley), fruit crops (e.g., tomato, apple, pear, strawberry, orange), forage crops (e.g., alfalfa), root vegetable crops (e.g., carrot, potato, sugar beets, yam), leafy vegetable crops (e.g., lettuce, spinach); vegetative crops for consumption (e.g. soybean and other legumes, squash, peppers, eggplant, celery etc), flowering plants (e.g., petunia, rose, chrysanthemum), conifers and pine trees (e.g., pine fir, spruce); poplar trees (e.g. P. tremula×P. alba); fiber crops (cotton, jute, flax, bamboo) plants used in phytoremediation (e.g., heavy metal accumulating plants); oil crops (e.g., sunflower, rape seed) and plants used for experimental purposes (e.g., Arabidopsis). Thus, the disclosed methods and compositions have use over a broad range of plants, including, but not limited to, species from the genera Asparagus, Avena, Brassica, Citrus, Citrullus, Capsicum, Cucurbita, Daucus, Erigeron, Glycine, Gossypium, Hordeum, Lactuca, Lolium, Lycopersicon, Malus, Manihot, Nicotiana, Orychophragmus, Oryza, Persea, Phaseolus, Pisum, Pyrus, Prunus, Raphanus, Secale, Solanum, Sorghum, Triticum, Vitis, Vigna, and Zea.

Assays for Determining Regulation of Gene Expression by TALE Fusion Proteins

A variety of assays can be used to determine the level of gene expression regulation by TALE-fusion proteins. The activity of a particular TALE-fusion proteins can be assessed using a variety of in vitro and in vivo assays, by measuring, e.g., protein or mRNA levels, product levels, enzyme activity, tumor growth; transcriptional activation or repression of a reporter gene; second messenger levels (e.g., cGMP, cAMP, IP3, DAG, Ca.sup.2+); cytokine and hormone production levels; and neovascularization, using, e.g., immunoassays (e.g., ELISA and immunohistochemical assays with antibodies), hybridization assays (e.g., RNase protection, northems, in situ hybridization, oligonucleotide array studies), colorimetric assays, amplification assays, enzyme activity assays, tumor growth assays, phenotypic assays, and the like.

TALE-fusion proteins are typically first tested for activity in vitro using cultured cells, e.g., 293 cells, CHO cells, VERO cells, BHK cells, HeLa cells, COS cells, plant cell lines, plant callous cultures and the like. Preferably, human cells are used. The TALE-fusion protein is often first tested using a transient expression system with a reporter gene, and then regulation of the target endogenous gene is tested in cells and in animals, both in vivo and ex vivo. The TALE fusion proteins can be recombinantly expressed in a cell, recombinantly expressed in cells transplanted into an animal or plant, or recombinantly expressed in a transgenic animal or plant, as well as administered as a protein to an animal, plant or cell using delivery vehicles described herein. The cells can be immobilized, be in solution, be injected into an animal, or be naturally occurring in a transgenic or non-transgenic animal.

Modulation of gene expression is tested using one of the in vitro or in vivo assays described herein. Samples or assays are treated with a TALE-fusion proteins and compared to control samples without the test compound, to examine the extent of modulation.

The effects of the TALE-fusion proteins can be measured by examining any of the parameters described above. Any suitable gene expression, phenotypic, or physiological change can be used to assess the influence of a TALE-fusion protein. When the functional consequences are determined using intact cells or animals, one can also measure a variety of effects such as tumor growth, neovascularization, hormone release, transcriptional changes to both known and uncharacterized genetic markers (e.g., northern blots or oligonucleotide array studies), changes in cell metabolism such as cell growth or pH changes, and changes in intracellular second messengers such as cGMP.

Preferred assays for TALE-fusion protein mediated regulation of endogenous gene expression can be performed in vitro. In one preferred in vitro assay format, TALE-fusion protein mediated regulation of endogenous gene expression in cultured cells is measured by examining protein production using an ELISA assay. The test sample is compared to control cells treated with an empty vector or an unrelated TALE-fusion protein that is targeted to another gene.

In another embodiment, TALE-fusion protein-mediated regulation of endogenous gene expression is determined in vitro by measuring the level of target gene mRNA expression. The level of gene expression is measured using amplification, e.g., using PCR, LCR, or hybridization assays, e.g., northern hybridization, RNase protection, dot blotting. RNase protection is used in one embodiment. The level of protein or mRNA is detected using directly or indirectly labeled detection agents, e.g., fluorescently or radioactively labeled nucleic acids, radioactively or enzymatically labeled antibodies, and the like, as described herein.

Alternatively, a reporter gene system can be devised using the target gene promoter operably linked to a reporter gene such as luciferase, green fluorescent protein, CAT, or beta-gal. The reporter construct is typically co-transfected into a cultured cell. After treatment with the TALE-fusion proteins of choice, the amount of reporter gene transcription, translation, or activity is measured according to standard techniques known to those of skill in the art.

Another example of a preferred assay format useful for monitoring TALE-fusion protein mediated regulation of endogenous gene expression is performed in vivo. This assay is particularly useful for examining TALE-fusions that inhibit expression of tumor promoting genes, genes involved in tumor support, such as neovascularization (e.g., VEGF), or that activate tumor suppressor genes such as p53. In this assay, cultured tumor cells expressing the TALE-fusions of choice are injected subcutaneously into an immune compromised mouse such as an athymic mouse, an irradiated mouse, or a SCID mouse. After a suitable length of time, preferably 4-8 weeks, tumor growth is measured, e.g., by volume or by its two largest dimensions, and compared to the control. Tumors that have statistically significant reduction (using, e.g., Student's T test) are said to have inhibited growth. Alternatively, the extent of tumor neovascularization can also be measured. Immunoassays using endothelial cell specific antibodies are used to stain for vascularization of the tumor and the number of vessels in the tumor. Tumors that have a statistically significant reduction in the number of vessels (using, e.g., Student's T test) are said to have inhibited neovascularization.

Transgenic and non-transgenic plants or animals as described above are also used as a preferred embodiment for examining regulation of endogenous gene expression in vivo. Transgenic organisms typically express the TALE-fusions of choice. Alternatively, organisms that transiently express the TALE-fusions of choice, or to which the TALE fusion proteins have been administered in a delivery vehicle, can be used. Regulation of endogenous gene expression is tested using any one of the assays described herein.

Nucleic Acids Encoding TALE-Fusion Proteins

Conventional viral and non-viral based gene transfer methods can be used to introduce nucleic acids encoding engineered TALE domain fusions in mammalian cells, in whole organisms or in target tissues. Such methods can be used to administer nucleic acids encoding TALE domain fusions to cells in vitro. Preferably, the nucleic acids encoding TALE domain fusions are administered for in vivo or ex vivo uses. Non-viral vector delivery systems include DNA plasmids, naked nucleic acid, and nucleic acid complexed with a delivery vehicle such as a liposome. Viral vector delivery systems include DNA and RNA viruses, which have either episomal or integrated genomes after delivery to the cell. For a review of gene therapy procedures, see Anderson, Science 256:808-813 (1992); Nabel & Felgner, TIBTECH 11:211-217 (1993); Mitani & Caskey, TIBTECH 11:162-166 (1993); Dillon, TIBTECH 11:167-175 (1993); Miller, Nature 357:455-460 (1992); Van Brunt, Biotechnology 6(10):1149-1154 (1988); Vigne, Restorative Neurology and Neuroscience 8:35-36 (1995); Kremer & Perricaudet, British Medical Bulletin 51(1):31-44 (1995); Haddada et al., in Current Topics in Microbiology and Immunology Doerfler and Bohm (eds) (1995); and Yu et al., Gene Therapy 1:13-26 (1994).

The use of RNA or DNA viral based systems for the delivery of nucleic acids encoding engineered TALE domain fusions takes advantage of highly evolved processes for targeting a virus to specific cells in the body and trafficking the viral payload to the nucleus. Viral vectors can be administered directly to patients (in vivo) or they can be used to treat cells in vitro and the modified cells are administered to patients (ex vivo). Conventional viral based systems for the delivery of TALE domain fusions could include retroviral, lentivirus, adenoviral, adeno-associated and herpes simplex virus vectors for gene transfer. Viral vectors are currently the most efficient and versatile method of gene transfer in target cells and tissues. Integration in the host genome is possible with the retrovirus, lentivirus, and adeno-associated virus gene transfer methods, often resulting in long term expression of the inserted transgene. Additionally, high transduction efficiencies have been observed in many different cell types and target tissues.

The tropism of a retrovirus can be altered by incorporating foreign envelope proteins, expanding the potential target population of target cells. Lentiviral vectors are retroviral vector that are able to transduce or infect non-dividing cells and typically produce high viral titers. Selection of a retroviral gene transfer system would therefore depend on the target tissue. Retroviral vectors are comprised of cis-acting long terminal repeats with packaging capacity for up to 6-10 kb of foreign sequence. The minimum cis-acting LTRs are sufficient for replication and packaging of the vectors, which are then used to integrate the therapeutic gene into the target cell to provide permanent transgene expression. Widely used retroviral vectors include those based upon murine leukemia virus (MuLV), gibbon ape leukemia virus (GaLV), Simian Immuno deficiency virus (SIV), human immuno deficiency virus (HIV), and combinations thereof (see, e.g., Buchscher et al., J. Virol. 66:2731-2739 (1992); Johann et al., J Virol. 66:1635-1640 (1992); Sommerfelt et al, Virol. 176:58-59 (1990); Wilson et al., J. Virol. 63:2374-2378 (1989); Miller et al., J. Virol. 65:2220-2224 (1991); PCT/US94/05700).

In applications where transient expression of the TALE domain fusions is preferred, adenoviral based systems are typically used. Adenoviral based vectors are capable of very high transduction efficiency in many cell types and do not require cell division. With such vectors, high titer and levels of expression have been obtained. This vector can be produced in large quantities in a relatively simple system. Adeno-associated virus (“AAV”) vectors are also used to transduce cells with target nucleic acids, e.g., in the in vitro production of nucleic acids and peptides, and for in vivo and ex vivo gene therapy procedures (see, e.g., West et al., Virology 160:38-47 (1987); U.S. Pat. No. 4,797,368; WO 93/24641; Kotin, Human Gene Therapy 5:793-801 (1994); Muzyczka, J. Clin. Invest. 94:1351 (1994). Construction of recombinant AAV vectors are described in a number of publications, including U.S. Pat. No. 5,173,414; Tratschin et al., Mol. Cell. Biol. 5:3251-3260 (1985); Tratschin, et al., Mol Cell. Biol. 4:2072-2081 (1984); Hermonat & Muzyczka, Proc Natl Acad Sci USA 81:6466-6470 (1984); and Samulski et al., J. Virol. 63:03822-3828 (1989).

In particular, at least six viral vector approaches are currently available for gene transfer in clinical trials, with retroviral vectors by far the most frequently used system. All of these viral vectors utilize approaches that involve complementation of defective vectors by genes inserted into helper cell lines to generate the transducing agent.

pLASN and MFG-S are examples are retroviral vectors that have been used in clinical trials (Dunbar et al., Blood 85:3048-305 (1995); Kohn et al., Nat. Med. 1:1017-102 (1995); Malech et al., Proc Natl Acad Sci USA 94:22 12133-12138 (1997)). PA317/pLASN was the first therapeutic vector used in a gene therapy trial. (Blaese et al., Science 270:475480 (1995)). Transduction efficiencies of 50% or greater have been observed for MFG-S packaged vectors. (Ellem et al., Immunol Immunother 44(1):10-20 (1997); Dranoff et al., Hum. Gene Ther. 0.1:111-2 (1997).

Recombinant adeno-associated virus vectors (rAAV) are a promising alternative to gene delivery systems based on the defective and nonpathogenic parvovirus adeno-associated type 2 virus. All vectors are derived from a plasmid that retains only the AAV 145 bp inverted terminal repeats flanking the transgene expression cassette. Efficient gene transfer and stable transgene delivery due to integration into the genomes of the transduced cell are key features for this vector system. (Wagner et al., Lancet 351:9117 1702-3 (1998), Kearns et al., Gene Ther. 9:748-55 (1996)).

Replication-deficient recombinant adenoviral vectors (Ad) are predominantly used for colon cancer gene therapy, because they can be produced at high titer and they readily infect a number of different cell types. Most adenovirus vectors are engineered such that a transgene replaces the Ad E1a, E1b, and E3 genes; subsequently the replication defector vector is propagated in human 293 cells that supply deleted gene function in trans. Ad vectors can transduce multiply types of tissues in vivo, including nondividing, differentiated cells such as those found in the liver, kidney and muscle system tissues. Conventional Ad vectors have a large carrying capacity. An example of the use of an Ad vector in a clinical trial involved polynucleotide therapy for antitumor immunization with intramuscular injection (Sterman et al., Hum. Gene Ther. 7:1083-9 (1998)). Additional examples of the use of adenovirus vectors for gene transfer include Rosenecker et al, Infection 24:1 5-10 (1996); Sterman et al., Hum. Gene Ther. 9:7 1083-1089 (1998); Welsh et al., Hum. Gene Ther. 2:205-18 (1995); Alvarez et al., Hum. Gene Ther. 5:597-613 (1997); Topf et al., Gene Ther. 5:507-513 (1998); Sterman et al., Hum. Gene Ther. 7:1083-1089 (1998); U.S. Patent Publication No. 2008/0159996.

Packaging cells are used to form virus particles that are capable of infecting a host cell. Such cells include 293 cells, which package adenovirus, and psi2 cells or PA317 cells, which package retrovirus. Viral vectors used in gene therapy are usually generated by producer cell line that packages a nucleic acid vector into a viral particle. The vectors typically contain the minimal viral sequences required for packaging and subsequent integration into a host, other viral sequences being replaced by an expression cassette for the protein to be expressed. The missing viral functions are supplied in trans by the packaging cell line. For example, AAV vectors used in gene therapy typically only possess ITR sequences from the AAV genome, which are required for packaging and integration into the host genome. Viral DNA is packaged in a cell line, which contains a helper plasmid encoding the other AAV genes, namely rep and cap, but lacking ITR sequences. The cell line is also infected with adenovirus as a helper. The helper virus promotes replication of the AAV vector and expression of AAV genes from the helper plasmid. The helper plasmid is not packaged in significant amounts due to a lack of ITR sequences. Contamination with adenovirus can be reduced by, e.g., heat treatment to which adenovirus is more sensitive than AAV.

In many gene therapy applications, it is desirable that the gene therapy vector be delivered with a high degree of specificity to a particular tissue type. A viral vector is typically modified to have specificity for a given cell type by expressing a ligand as a fusion protein with a viral coat protein on the viruses outer surface. The ligand is chosen to have affinity for a receptor known to be present on the cell type of interest. For example, Han et al., Proc Natl Acad Sci USA 92:9747-9751 (1995), reported that Moloney murine leukemia virus can be modified to express human heregulin fused to gp70, and the recombinant virus infects certain human breast cancer cells expressing human epidermal growth factor receptor. This principle can be extended to other pairs of virus, expressing a ligand fusion protein and target cell expressing a receptor. For example, filamentous phage can be engineered to display antibody fragments (e.g., FAB or Fv) having specific binding affinity for virtually any chosen cellular receptor. Although the above description applies primarily to viral vectors, the same principles can be applied to nonviral vectors. Such vectors can be engineered to contain specific uptake sequences thought to favor uptake by specific target cells.

Gene therapy vectors can be delivered in vivo by administration to an individual patient, typically by systemic administration (e.g., intravenous, intraperitoneal, intramuscular, subdermal, or intracranial infusion) or topical application, as described below. Alternatively, vectors can be delivered to cells ex vivo, such as cells explanted from an individual patient (e.g., lymphocytes, bone marrow aspirates, tissue biopsy) or universal donor hematopoietic stem cells, followed by reimplantation of the cells into a patient, usually after selection for cells which have incorporated the vector.

Ex vivo cell transfection for diagnostics, research, or for gene therapy (e.g., via re-infusion of the transfected cells into the host organism) is well known to those of skill in the art. In a preferred embodiment, cells are isolated from the subject organism, transfected with a TALE fusion nucleic acid (gene or cDNA), and re-infused back into the subject organism (e.g., patient). Various cell types suitable for ex vivo transfection are well known to those of skill in the art (see, e.g., Freshney et al., Culture of Animal Cells, A Manual of Basic Technique (3rd ed. 1994)) and the references cited therein for a discussion of how to isolate and culture cells from patients).

In one embodiment, stem cells are used in ex vivo procedures for cell transfection and gene therapy. The advantage to using stem cells is that they can be differentiated into other cell types in vitro, or can be introduced into a mammal (such as the donor of the cells) where they will engraft in the bone marrow. Methods for differentiating CD34+ cells in vitro into clinically important immune cell types using cytokines such a GM-CSF, IFN-.gamma. and TNF-alpha are known (see Inaba et al., J. Exp. Med. 176:1693-1702 (1992)).

Stem cells are isolated for transduction and differentiation using known methods. For example, stem cells are isolated from bone marrow cells by panning the bone marrow cells with antibodies which bind unwanted cells, such as CD4+ and CD8+(T cells), CD45+(panb cells), GR-1 (granulocytes), and Tad (differentiated antigen presenting cells) (see Inaba et al., J. Exp. Med. 176:1693-1702 (1992)). Exemplary stem cells include human embryonic stem cells (hES), induced pluripotent stem cells (iPSC), hematopoietic stem cells, mesenchymal stem cells, neuronal stem cells, and muscle stem cells.

Vectors (e.g., retroviruses, adenoviruses, liposomes, etc.) containing therapeutic TALE domain fusion nucleic acids can be also administered directly to the organism for transduction of cells in vivo. Alternatively, naked DNA can be administered. Administration is by any of the routes normally used for introducing a molecule into ultimate contact with blood or tissue cells. Suitable methods of administering such nucleic acids are available and well known to those of skill in the art, and, although more than one route can be used to administer a particular composition, a particular route can often provide a more immediate and more effective reaction than another route.

Pharmaceutically acceptable carriers are determined in part by the particular composition being administered, as well as by the particular method used to administer the composition. Accordingly, there is a wide variety of suitable formulations of pharmaceutical compositions of the present invention, as described below (see, e.g., Remington's Pharmaceutical Sciences, 17th ed., 1989).

Pharmaceutical Compositions and Administration

TALE-fusions and expression vectors encoding TALE fusions can be administered directly to the patient for modulation of gene expression and for therapeutic or prophylactic applications, for example, cancer, ischemia, diabetic retinopathy, macular degeneration, rheumatoid arthritis, psoriasis, HIV infection, sickle cell anemia, Alzheimer's disease, muscular dystrophy, neurodegenerative diseases, vascular disease, cystic fibrosis, stroke, and the like. Examples of microorganisms that can be inhibited by TALE fusion protein gene therapy include pathogenic bacteria, e.g., chlamydia, rickettsial bacteria, mycobacteria, staphylococci, streptococci, pneumococci, meningococci and conococci, klebsiella, proteus, serratia, pseudomonas, legionella, diphtheria, salmonella, bacilli, cholera, tetanus, botulism, anthrax, plague, leptospirosis, and Lyme disease bacteria; infectious fungus, e.g., Aspergillus, Candida species; protozoa such as sporozoa (e.g., Plasmodia), rhizopods (e.g., Entamoeba) and flagellates (Trypanosoma, Leishmania, Trichomonas, Giardia, etc.); viral diseases, e.g., hepatitis (A, B, or C), herpes virus (e.g. VZV, HSV-1, HSV-6, HSV-II, CMV, and EBV), HIV, Ebola, adenovirus, influenza virus, flaviviruses, echovirus, rhinovirus, coxsackie virus, comovirus, respiratory syncytial virus, mumps virus, rotavirus, measles virus, rubella virus, parvovirus, vaccinia virus, HTLV virus, dengue virus, papillomavirus, poliovirus, rabies virus, and arboviral encephalitis virus, etc.

Administration of therapeutically effective amounts is by any of the routes normally used for introducing TALE-fusions into ultimate contact with the tissue to be treated. The TALE-fusions are administered in any suitable manner, preferably with pharmaceutically acceptable carriers. Suitable methods of administering such modulators are available and well known to those of skill in the art, and, although more than one route can be used to administer a particular composition, a particular route can often provide a more immediate and more effective reaction than another route.

Formulations suitable for parenteral administration, such as, for example, by intravenous, intramuscular, intradermal, and subcutaneous routes, include aqueous and non-aqueous, isotonic sterile injection solutions, which can contain antioxidants, buffers, bacteriostats, and solutes that render the formulation isotonic with the blood of the intended recipient, and aqueous and non-aqueous sterile suspensions that can include suspending agents, solubilizers, thickening agents, stabilizers, and preservatives. In the practice of this invention, compositions can be administered, for example, by intravenous infusion, orally, topically, intraperitoneally, intravesically or intrathecally. The formulations of compounds can be presented in unit-dose or multi-dose sealed containers, such as ampules and vials. Injection solutions and suspensions can be prepared from sterile powders, granules, and tablets of the kind previously described.

Regulation of Gene Expression in Plants

TALE-fusions can be used to engineer plants for traits such as increased disease resistance, modification of structural and storage polysaccharides, flavors, proteins, and fatty acids, fruit ripening, yield, color, nutritional characteristics, improved storage capability, drought or submergence/flood tolerance, and the like. In particular, the engineering of crop species for enhanced oil production, e.g., the modification of the fatty acids produced in oilseeds, is of interest. See, e.g., U.S. Pat. No. 7,262,054; and U.S. Patent Publication Nos. 2008/0182332 and 20090205083.

Seed oils are composed primarily of triacylglycerols (TAGs), which are glycerol esters of fatty acids. Commercial production of these vegetable oils is accounted for primarily by six major oil crops (soybean, oil palm, rapeseed, sunflower, cotton seed, and peanut.) Vegetable oils are used predominantly (90%) for human consumption as margarine, shortening, salad oils, and flying oil. The remaining 10% is used for non-food applications such as lubricants, oleochemicals, biofuels, detergents, and other industrial applications.

The desired characteristics of the oil used in each of these applications varies widely, particularly in terms of the chain length and number of double bonds present in the fatty acids making up the TAGs. These properties are manipulated by the plant in order to control membrane fluidity and temperature sensitivity. The same properties can be controlled using TALE domain fusions to produce oils with improved characteristics for food and industrial uses.

The primary fatty acids in the TAGs of oilseed crops are 16 to 18 carbons in length and contain 0 to 3 double bonds. Palmitic acid (16:0 [16 carbons: 0 double bonds]), oleic acid (18:1), linoleic acid (18:2), and linolenic acid (18:3) predominate. The number of double bonds, or degree of saturation, determines the melting temperature, reactivity, cooking performance, and health attributes of the resulting oil.

The enzyme responsible for the conversion of oleic acid (18:1) into linoleic acid (18:2) (which is then the precursor for 18:3 formation) is DELTA12-oleate desaturase, also referred to as omega-6 desaturase. A block at this step in the fatty acid desaturation pathway should result in the accumulation of oleic acid at the expense of polyunsaturates.

In one embodiment proteins containing TALE domain(s) are used to regulate expression of the FAD2-1 gene in soybeans. Two genes encoding microsomal DELTA.6 desaturases have been cloned recently from soybean, and are referred to as FAD2-1 and FAD2-2 (Heppard et al., Plant Physiol. 110:311-319 (1996)). FAD2-1 (delta 12 desaturase) appears to control the bulk of oleic acid desaturation in the soybean seed. TALE-fusions can thus be used to modulate gene expression of FAD2-1 in plants. Specifically, TALE domain fusions can be used to inhibit expression of the FAD2-1 gene in soybean in order to increase the accumulation of oleic acid (18:1) in the oil seed. Moreover, TALE-fusions can be used to modulate expression of any other plant gene, such as delta-9 desaturase, delta-12 desaturases from other plants, delta-15 desaturase, acetyl-CoA carboxylase, acyl-ACP-thioesterase, ADP-glucose pyrophosphorylase, starch synthase, cellulose synthase, sucrose synthase, senescence-associated genes, heavy metal chelators, fatty acid hydroperoxide lyase, polygalacturonase, EPSP synthase, plant viral genes, plant fungal pathogen genes, and plant bacterial pathogen genes.

Functional Genomics Assays

TALE-fusions also have use for assays to determine the phenotypic consequences and function of gene expression. The recent advances in analytical techniques, coupled with focussed mass sequencing efforts have created the opportunity to identify and characterize many more molecular targets than were previously available. This new information about genes and their functions will speed along basic biological understanding and present many new targets for therapeutic intervention. In some cases analytical tools have not kept pace with the generation of new data. An example is provided by recent advances in the measurement of global differential gene expression. These methods, typified by gene expression microarrays, differential cDNA cloning frequencies, subtractive hybridization and differential display methods, can very rapidly identify genes that are up or down-regulated in different tissues or in response to specific stimuli. Increasingly, such methods are being used to explore biological processes such as, transformation, tumor progression, the inflammatory response, neurological disorders etc. One can now very easily generate long lists of differentially expressed genes that correlate with a given physiological phenomenon, but demonstrating a causative relationship between an individual differentially expressed gene and the phenomenon is difficult. Until now, simple methods for assigning function to differentially expressed genes have not kept pace with the ability to monitor differential gene expression.

Using conventional molecular approaches, over expression of a candidate gene can be accomplished by cloning a full-length cDNA, subcloning it into a mammalian expression vector and transfecting the recombinant vector into an appropriate host cell. This approach is straightforward but labor intensive, particularly when the initial candidate gene is represented by a simple expressed sequence tag (EST). Under expression of a candidate gene by “conventional” methods is yet more problematic. Antisense methods and methods that rely on targeted ribozymes are unreliable, succeeding for only a small fraction of the targets selected. Gene knockout by homologous recombination works fairly well in recombinogenic stem cells but very inefficiently in somatically derived cell lines. In either case large clones of syngeneic genomic DNA (on the order of 10 kb) should be isolated for recombination to work efficiently.

The TALE-fusion technology can be used to rapidly analyze differential gene expression studies. Engineered TALE domain fusions can be readily used to up or down-regulate any endogenous target gene. Very little sequence information is required to create a gene-specific DNA binding domain. This makes the TALE domain fusions technology ideal for analysis of long lists of poorly characterized differentially expressed genes. One can simply build a TALE-based DNA-binding domain for each candidate gene, create chimeric up and down-regulating artificial transcription factors and test the consequence of up or down-regulation on the phenotype under study (transformation, response to a cytokine etc.) by switching the candidate genes on or off one at a time in a model system.

This specific example of using engineered TALE domain fusions to add functional information to genomic data is merely illustrative. Any experimental situation that could benefit from the specific up or down-regulation of a gene or genes could benefit from the reliability and ease of use of engineered TALE-fusions.

Additionally, greater experimental control can be imparted by TALE domain fusions than can be achieved by more conventional methods. This is because the production and/or function of an engineered TALE-fusions can be placed under small molecule control. Examples of this approach are provided by the Tet-On system, the ecdysone-regulated system and a system incorporating a chimeric factor including a mutant progesterone receptor. These systems are all capable of indirectly imparting small molecule control on any endogenous gene of interest or any transgene by placing the function and/or expression of a ZFP regulator under small molecule control.

Transgenic Organisms

A further application of the TALE-fusion technology is manipulating gene expression and/or altering the genome to produce transgenic animals or plants. As with cell lines, over-expression of an endogenous gene or the introduction of a heterologous gene to a transgenic animal, such as a transgenic mouse, is a fairly straightforward process. Similarly, production of transgenic plants is well known. The TALE domain fusions technology described herein can be used to readily generate transgenic animals and plants.

The use of engineered TALE domain fusions to manipulate gene expression can be restricted to adult animals using the small molecule regulated systems described in the previous section. Expression and/or function of a TALE domain-based repressor can be switched off during development and switched on at will in the adult animals. This approach relies on the addition of the TALE-fusions expressing module only; homologous recombination is not required. Because the TALE domain fusions repressors are trans dominant, there is no concern about germline transmission or homozygosity. These issues dramatically affect the time and labor required to go from a poorly characterized gene candidate (a cDNA or EST clone) to a mouse model. This ability can be used to rapidly identify and/or validate gene targets for therapeutic intervention, generate novel model systems and permit the analysis of complex physiological phenomena (development, hematopoiesis, transformation, neural function etc.). Chimeric targeted mice can be derived according to Hogan et al., Manipulating the Mouse Embryo: A Laboratory Manual, (1988); Teratocarcinomas and Embryonic Stem Cells: A Practical Approach, Robertson, ed., (1987); and Capecchi et al., Science 244:1288 (1989).

Genetically modified animals may be generated by deliver of the nucleic acid encoding the TALE fusion into a cell or an embryo. Typically, the embryo is a fertilized one cell stage embryo. Delivery of the nucleic acid may be by any of the methods known in the art including micro injection into the nucleus or cytoplasm of the embryo. TALE fusion encoding nucleic acids may be co-delivered with donor nucleic acids as desired. The embryos are then cultured as in known in the art to develop a genetically modified animal.

In one aspect of the invention, genetically modified animals in which at least one chromosomal sequence encoding a gene or locus of interest has been edited are provided. For example, the edited gene may become inactivated such that it is not transcribed or properly translated. Alternatively, the sequence may be edited such that an alternate form of the gene is expressed (e.g. insertion (knock in) or deletion (knock out) of one or more amino acids in the expressed protein). In addition, the gene of interest may comprise an inserted sequence such as a regulatory region. The genetically modified animal may be homozygous for the edited sequence or may be heterozygous. In some embodiments, the genetically modified animal may have sequence inserted (knocked in) in a ‘safe harbor’ locus such as the Rosa26, HPRT, CCR5 or AAVS1 (PPP1R12C) loci. These knock in animals may be additionally edited at other chromosomal loci. In some embodiments, the sequences of interest are inserted into the safe harbor without any selection markers, and/or without a promoter and so rely on the endogenous promoter to drive expression. In some aspects, the genetically modified animal may be “humanized” such that certain genes specific to the host species animal are replaced with the human homolog. In this way, genetically modified animals are produced with a human gene expressed (e.g. Factor IX) to allow for the development of an animal model system to study the human gene, protein or disease. In some embodiments, the gene of interest may further comprise a recombinase recognition site such as loxP or FRT for recognition of the cognate recombinase Cre and FLP, respectively, which can flank the inserted gene(s) of interest. Genes may be inserted containing the nuclease sites such that crossing the genetically modified animal with another genetically modified animal expressing the cognate recombinase (e.g Cre) will result in progeny that lack the inserted gene.

Applications

The disclosed methods and compositions can be used to control gene regulation at a desired locus. Genes of choice may be activated or repressed, depending on the transcriptional regulatory domain that is fused to the TALE-repeat domain. TALE activators may be targeted to pluripotency-inducing genes for the goal of producing iPSCs from differentiated cells. This may be of use for in vitro and in vivo model development for specific disease states and for developing cell therapeutics derived from iPSCs.

The TALE-fusions may be useful themselves as therapeutic agents, especially in immune privileged tissues such as in the brain or eye. Designed activators, for example, are especially useful for increasing the dose of a gene product that requires natural splice variant ratios for proper function (e.g. VEGF), or for genes that are toxic where overexpressed. Transient exposure to designed TALE regulators may also allow permanent switching of gene expression status via the use of functional domain that impose epigenetic changes. This technology could provide additional utility for generating stem cells and controlling their differentiation pathways. Additionally, TALE-fusions may be of use in immunosuppressed patients.

The disclosed methods and compositions can also be used for genomic editing of any gene or genes. In certain applications, the methods and compositions can be used for inactivation of genomic sequences. To date, cleavage-based methods have been used to target modifications to the genomes of at least nine higher eukaryotes for which such capabilities were previously unavailable, including economically important species such as corn and rat. In other applications, the methods and compositions allow for generation of random mutations, including generation of novel allelic forms of genes with different expression or biological properties as compared to unedited genes or integration of humanized genes, which in turn allows for the generation of cell or animal models. In other applications, the methods and compositions can be used for creating random mutations at defined positions of genes that allows for the identification or selection of animals carrying novel allelic forms of those genes. In other applications, the methods and compositions allow for targeted integration of an exogenous (donor) sequence into any selected area of the genome. Regulatory sequences (e.g. promoters) could be integrated in a targeted fashion at a site of interest. By “integration” is meant both physical insertion (e.g., into the genome of a host cell) and, in addition, integration by copying of the donor sequence into the host cell genome via the specialized nucleic acid information exchange process that occurs during homology-directed DNA repair.

Donor sequences can also comprise nucleic acids such as shRNAs, miRNAs etc. These small nucleic acid donors can be used to study their effects on genes of interest within the genome. Genomic editing (e.g., inactivation, integration and/or targeted or random mutation) of an animal gene can be achieved, for example, by a single cleavage event, by cleavage followed by non-homologous end joining, by cleavage followed by homology-directed repair mechanisms, by cleavage followed by physical integration of a donor sequence, by cleavage at two sites followed by joining so as to delete the sequence between the two cleavage sites, by targeted recombination of a missense or nonsense codon into the coding region, by targeted recombination of an irrelevant sequence (i.e., a “stuffer” sequence) into the gene or its regulatory region, so as to disrupt the gene or regulatory region, or by targeting recombination of a splice acceptor sequence into an intron to cause mis-splicing of the transcript. In some applications, transgenes of interest may be integrated into a safe harbor locus within a mammalian or plant genome using TALEN-induced DSB at a specified location. See, U.S. Patent Publication Nos. 20030232410; 20050208489; 20050026157; 20050064474; 20060188987; 20060063231; and International Publication WO 07/014275, the disclosures of which are incorporated by reference in their entireties for all purposes. These TALENs may also be supplied as components of kits for targeted genetic manipulation.

TALE-repeat domains, optionally with novel or atypical RVDs, and moreover optionally attached to N-cap and/or C-cap residues, can also be fused to DNA manipulating enzymes such as recombinases, transposases, resolvases or integrases. Thus these domains can be used to make targeted fusion proteins that would allow the development of such tools and/or therapeutics as targeted transposons and the like. Additionally, a TALE-repeat domain, optionally attached to N-cap and C-cap residues, may be fused to nuclease domains to create designer restriction enzymes. For example, a TALE-repeat domain, optionally attached to N-cap and C-cap residues, may be fused to a single-chain FokI domain (wherein two FokI cleavage half domains are joined together using a linker of choice) such that treatment of a DNA preparation with the nuclease fusion can allow cleavage to occur exactly at the desired location. This technology would be useful for cloning and manipulation of DNA sequences that are not readily approached with standard restriction enzymes. Such a system would also be useful in specialized cell systems used in manufacturing. For example, the CHO-derived cell lines do not have an endogenously active transposase/integrase system. TALE-transposase/integrase systems could be developed for specific targeting in CHO cells and could be useful for knock out/knock in, genome editing etc due to the highly specific nature of the TALE DNA binding domain.

TALE-fusion proteins can be used to prevent binding of specific DNA-binding proteins to a given locus. For example, a natural regulatory protein may be blocked from binding to its natural target in a promoter simply because an engineered TALE protein has been expressed in the host cell and it occupies the site on the DNA, thus preventing regulation by the regulatory protein.

TALE-fusion proteins may be engineered to bind to RNA. In this way, for example, splice donors and/or splice acceptor sites could be masked and would prevent splicing at specific locations in a mRNA. In other aspects, a TALE may be engineered to bind specific functional RNAs such as shRNAs, miRNA or RNAis, for example.

TALE fusion proteins can be useful in diagnostics. For example, the proteins may be engineered to recognize certain sequences in the genome to identify alleles known to be associated with a specific disease. For example, TALE-fusions with a specified number of TALE repeat units may be utilized as a “yard stick” of sorts to measure the number of trinucleotide repeats in patients with the potential of having a trinucleotide repeat disorder (e.g. Huntingdon's Disease) to determine the likelihood of becoming afflicted with one of these diseases or to prognosticate the severity of the symptoms. These fusion proteins may also be supplied as components of diagnostic kits to allow rapid identification of genomic markers of interest. Additionally, these proteins may be purified from cells and used in diagnostic kits or for diagnostic reagents for uses such as analyzing the allele type of a gene of interest, measuring mRNA expression levels etc. The TALE fusions may be attached to silicon chips or beads for multichannel or microfluidic analyses.

TALE fusions may be useful in manufacturing settings. TALE-transcription factor fusions or TALENs may be used in cell lines of interest (e.g. CHO cells) or in algae (e.g. for biofuel production).

There are a variety of applications for TALE fusion proteins mediated genomic editing of a gene or genomic loci. The methods and compositions described herein allow for the generation of models of human diseases and for plant crops with desired characteristics.

All publications and patent applications cited in this specification are herein incorporated by reference as if each individual publication or patent application were specifically and individually indicated to be incorporated by reference.

Although the foregoing invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it will be readily apparent to one of ordinary skill in the art in light of the teachings of this invention that certain changes and modifications may be made thereto without departing from the spirit or scope of the appended claims.

EXAMPLES Example 1: Cloning of a Natural TALE from Xanthomonas axonopodis

To identify a natural TALE protein that could serve as an initial design framework, a canonical, natural TALE that both exhibited a high degree of specificity as well as evidence of target sequence binding in mammalian cells was identified. Specifically, a TALE protein containing 12.5 TALE repeats (12 full repeats and a half repeat referred to as TALE 13) was cloned from Xanthomonas axonopodis by PCR amplification using the following primer pair: pthA_d152N_EcoR, ACGTGGATTCATGGTGGATCTACGCACGCTC (SEQ ID NO:52) and pthA_Sac2_Rev, TACGTCCGCGGTCCTGAGGCAATAGCTCCATCA (SEQ ID NO:53) The primer pair was originally designed to amplify the AvrBs3 gene with the N-terminal 152 amino acids truncation. It has been previously shown that these sequences are necessary for transport into plant cells, but otherwise are dispensable for function (see Szurek et at (2002) Mol. Micro 46(1) p. 13-23). Several TALE proteins, characterized by the highly conserved sequences with the variation of the numbers of central tandem repeats, were isolated by PCR with these primer pairs. With the exception of TALE15, which has been reported as hssB3.0 (Shiotani et al (2007) J. Bacteriol 189 (8): 3271-9) the other TALE proteins isolated appear as novel proteins, as they have not been reported in the public literature. These include TALE13, TALES, and TALE16, with 13, 9, and 16 TALE repeats, respectively.

The domain map of TALE13 (with the length of the N-cap inferred) is shown in FIG. 1A and the sequence indicating the domains and the amino acids that determine the DNA sequence that the protein interacts with are indicated in FIG. 1B, along with indicators of the positional numbering system used in this work.

Example 2: Truncation of TALE13 and Other TALEs and Effects on DNA Binding

As an initial investigation of the range of capping sequences that provide maximal activity, several truncations of the TALE were made. These truncations are shown below in Table 4.

TABLE 4 TALE truncation characteristics N Term N Term Nuclear Clone +288 to +137 to Repeat Leucine localization Acidic number +138 +37 R0 units R1/2 rich region domain domain #1 (−) (+) (+) (+) (+) (+) (+) (+) #2 (−) (+) (+) (+) (+) (+) (−) (−) #3 (−) (+) (+) (+) (+) (−) (−) (−) #4 (−) (−) (+) (+) (+) (+) (−) (−) #5 (−) (−) (−) (+) (+) (−) (−) (−) #6 (−) (+) (+) (+) (+) (+) (−) (−) #7 (−) (+/−) (+) (+) (+) (+) (−) (−) Note: (+) indicates the presence of the region while (−) indicates its absence

The regions of the truncations are numbered as follows: On the N-terminus, the end point is represented by a number that enumerates the number of amino acid residues in an N-terminal direction from the first base of the first true TALE repeat (see FIG. 1B). For example, a label of N+91 describes a truncation on the N-terminus that leaves intact the 91 amino acids in the N-terminal direction from the N-terminus of the first true repeat. On the C terminus, the end point is represented by the number of amino acids in the C-terminal direction from the last amino acid of the last full TALE repeat. Truncation #1, termed TALE-13, clone #1, has the N-terminal 152 amino acids of the full length TALE protein removed and a single methionine residue added to the resulting N terminus and thus has an N+137 endpoint (N-cap), making this clone approximately 2.5 kb in length. Truncation #2, also has the N-terminal 152 amino acids of the full length TALE protein removed, and a single methionine residue added to the resulting N-terminus and thus has an N+137 endpoint, as well as the C-terminal sequences downstream of the 5′ edge of the NLS, making this clone approximately 2.0 kb in length. Truncation #3 is similar to clone #2 except that it has the leucine-rich region deleted (the leucine-rich region is C-terminal to the half-repeat and extends to C+52 of the C-cap), making this clone approximately 1.6 kb in length. Truncation #4 is similar to clone #2 except that on the N-terminus, it has been deleted all the way up and including the R0 repeat sequence, making this clone approximately 1.6 kb in length. Truncation #5 is similar to clone #4 except that its deletion on the C-terminal side includes the leucine-rich sequence (similar to clone #2), making this clone approximately 1.4 kb in length. The deduced target sequence of the full length TALE 13 protein is TATAAATACCTTCT (SEQ ID NO:54), although there has not yet been an endogenous target site identified for this protein. Truncation #6 has 152 amino acids deleted from the N-terminus and in the C-terminal regions is similar to clone #2 except that 43 additional amino acids have been deleted. Truncation #7 has 165 amino acids deleted from the N-terminus and has the same C-terminal deletion as clone #6. Truncations #6 and #7 are discussed below.

A standard SELEX assay was run on the truncated TALE proteins to identify the DNA sequence these proteins bind to (for SELEX methodology, see Perez, E. E. et al. Nature Biotech. 26, 808-816 (2008)), and the results are presented in Tables 5 and 6. The experiment presented in Table 5 was performed with target library N18TA. The N18TA library includes a DNA duplex with sequence:

N18TA:

The data is presented below in Table 5 as a base frequency matrix. At each position in these matrices, the box indicates the expected RVD target base; numbers indicate the relative frequency of each recovered base type where 1.0 indicated 100%.

TABLE 5 SELEX results with TALE 13, clone #1

The TALE 13 clone #1 protein appears to be highly selective in its binding despite lacking the N-terminal 152 amino acids. The SELEX data for TALE 13, clone #2 is presented in Table 6. In this figure, the SELEX was repeated with two different libraries of target sequences, and gave similar results with both libraries.

TABLE 6 SELEX Results with TALE 13, clone #2

When clones #3, 4 and 5 were subjected to the SELEX procedure, no consensus sequences were detected. Thus it appears that the TALE binding domains require N- and C-terminal cap sequences comprised in from clone #2 to yield a consensus sequence in this assay. Additional truncations were made and tested for activity using a DNA binding ELISA assay essentially as described in Bartsevich et al., Stem Cells. 2003; 21:632-7. The truncations are presented below in Table 7, which also includes the ELISA results. The starting N-terminus in these truncations is at amino acid 152, identical to the N-terminus in the #1, #2, and #3 truncations discussed above. In this fine-scale truncation series, the end points are as follows.

TABLE 7 ELISA results on fine truncations of TALE13 ELISA results (relative N-Cap C-Cap fluorescence units) N + 137 C + 52 56, 32 N + 121 C + 52 8, 9 N + 111 C + 52 10, 12 N + 100 C + 52 8, 9 N + 91 C + 52  9, 10 N + 137 C + 95 131, 82, 44 N + 100 C + 115 10, 14 N + 91 C + 115 12, 13 N + 0 C + 278 10 N + 0 C + 95 9 N + 0 C + 27 8 N + 137 C + 278 12 N + 137 C + 27 10

These data suggest that the efficient TALE binding in this in vitro assay requires residues from between N+122 and N+137 and also from between C+53 and C+95 (N-cap residues up to and including N+121 were not sufficient for robust binding and C-cap residues up to and including C+52 were not sufficient for robust binding).

The preliminary mapping studies allowed the estimation of the minimal N-cap and C-cap sequences of the Xanthomonas TALE to achieve optimal binding activity. For the N-terminal cap, it appears that the sequence comprising some number of amino acids between the N+122 and N+137 amino acids prior to the beginning to the first true repeat are required for DNA binding activity. Similar cap examples for the Ralstonia caps can be made based on structural homology to the Xanthomonas TALEs (see below in Table 8). In the C-terminal caps, the bold amino acids indicate the RVDs.

Example 3: Binding Specificity for Natural TALE Proteins 9 and 16

Two additional natural TALE proteins were subjected to the SELEX procedure to identify the target DNA sequences that these proteins bind. TALE 9 has 8.5 TALE repeats that specify the following DNA target: TANAAACCTT (SEQ ID NO:56), while TALE16 has 15.5 TALE repeats that predict the following target: TACACATCTTTAACACT (SEQ ID NO:57). The data are presented in Tables 9 and 10. In Table 9, the TALE 9 protein in the clone #2 configurations was used and the results are shown. As with TALE 13 clone #2, this experiment was repeated with a second partially randomized DNA library and gave similar data as the first library. As described above for TALE 13, TALE 9 is highly specific for its target sequence.

TABLE 9 SELEX results with TALE 9, clone #2

Table 10 shows the SELEX data for the TALE 16 protein with the N18TA library and again demonstrates a high degree of sequence specificity for the target identified.

TABLE 10 SELEX results with TALE 16, clone #2

Additional truncations were made in the TALE proteins to further investigate the conditions for efficient DNA binding. Table 4 above depicts these truncations. When TALE 9 was tested in the clone #6 truncation (Table 11) the DNA binding specificity was maintained (compare Table 11 with Table 9).

TABLE 11 SELEX results with TALE 9, clone #6

Example 4: Reporter Gene Activation by TALE-Fusion Proteins in Mammalian Cells

To investigate the functional activity of the TALE domain fusions in mammalian cells, engineered reporter constructs were made as follows. One or more copies of the target sequences for the cloned TALE 13 or TALE 15 were inserted in a reporter construct between the NheI and Bgl II sites thereby placing the targets upstream from the firefly luciferase expression unit driven by the minimal SV40 promoter in the pGL3 plasmid (Promega) (see FIG. 2). The promoter region of the pGL3 plasmid is shown in FIG. 2A and the sequence containing the two predicted target sites for TALE13 is shown in FIG. 2B. In the experiment depicted in FIG. 3, the TALE protein construct, together with the reporter plasmid containing 2 targets (FIG. 3A), and an expression construct containing Renilla luciferase (Promega) as an internal control, were co-transfected into human 293 cells. The firefly luciferase activity induced by each TALE protein was then analyzed 2 days after transfection. In response to multiple targets, TALE VP16 fusions can synergistically activate the reporter gene expression in mammalian cells (FIG. 3). Additionally, as shown in FIG. 4B, TALE proteins with addition of the VP16 activation domain (TR13-VP16 and TR15-VP16) activate the luciferase reporter gene. Expression of the natural TALE protein without the VP16 domain does not activate luciferase (TR13 and TR15). Thus the reporter gene activation is observed only when the correct targets are matched with their corresponding TALE fusions, suggesting that the transcriptional activation results from targeted DNA binding.

Next, the TALE target sequences were inserted in both distal and proximal locations relative to the targeted promoter. In this experiment, the TALE13 target was used as shown in FIG. 5A where four target sequences were inserted either upstream (for example “R13×4”) or downstream (“R13×4D”) of the promoter. The results, shown in FIG. 5B demonstrate that optimal activation is seen when the TALE13 binding sites were placed upstream in close proximity to the promoter of interest.

Example 5: Construction of an Artificial TALE Transcription Factor

Having demonstrated that TALE proteins can be linked to a transcriptional regulatory domain to modulate reporter gene expression in mammalian cells, experiments were performed to engineer TALE transcription factors with desired targeting specificities. Silent mutations (i.e. a change in the nucleotide sequence without an alteration of amino acid sequence) of TR13 VP16 were introduced to create two unique restriction sites, ApaI and HpaI, at the beginning of the first tandem repeat and the end of last tandem repeat, respectively. These ApaI and HpaI sites were then used for cloning the synthetic tandem repeats into the TR13 VP16 backbone to generate the engineered TALEs with complete N- and C-terminal sequences flanking the tandem repeats, as well as the VP16 activation domain.

The targeted sequence was GGAGCCATCTGGCCGGGT (SEQ ID NO:58) located within the NT3 promoter sequence. Previously a ZFP TF 23570 targeting to this sequence has shown to activate the endogenous NTF3 gene expression (See co-owned U.S. Provisional Patent application 61/206,770). The 17.5 tandem repeats from the TALE AvrBs3 were used as a backbone to engineer TALE18 (also termed “NT-L”) such that the tandem repeats of the engineered TALE18 amino acid sequences were altered to specify the intended target nucleotide. The amino acid sequence of the DNA-binding domain from engineered TALE18 is shown below in Table 12, where the RVDs are shown boxed in bold:

TABLE 12 DNA-binding domain of engineered TALE18 (NT-L) Engineered TALE18 17.5 repeats

In addition to the four RVDs used in previous engineering efforts (NI, HD, NN, and NG to target A, C, G and T, respectively) we also incorporated the NK RVD in a subset of TALE repeats at positions corresponding to G nucleotides in the DNA target site as it was observed with a cognate target site guanine in two naturally occurring proteins (see Moscou et al, ibid). Consistent with earlier experimental studies (see Boch et al, ibid), we found that on average NI, HD, NG showed a strong preference for adenine, cytosine, and thymine respectively and NN showed a preference for guanine, but can also bind adenine. In contrast, the NK RVD shows a strong preference for guanine, representing a potential improvement for engineered TALE proteins that target sites including at least one guanine.

The DNA sequence coding for the 17.5 tandem repeats of the engineered TALE18 was then derived from the amino acid sequence and synthesized by 84 overlapping oligos, each about 40 nucleotides in length, as follows. First, the whole 1.8 kb DNA sequences were divided into 11 blocks, and overlapping oligos covering each block was assembled by PCR-based method; the 11 blocks was then fused together into 4 bigger blocks by overlapping PCR and finally, the 4 blocks were assembled into the full length by overlapping PCR using the outmost primer pairs. The synthesized tandem repeats was then sequence confirmed and cloned into the ApaI and HpaI sites of TR13-VP16, as described above, to generate the expression construct of engineered TALE18 (NT-L) targeting to the NT-3 promoter (R23570V).

The specificity of this engineered protein (termed NT-L) was then determined by SELEX, and the results are shown below in Table 13. As can be seen, the data demonstrate that it is possible to engineer an entirely novel TALE protein to bind to a desired sequence. The SELEX selection was also performed with NT-L in the clone #6 truncation (see above) as is also shown below in Table 13 demonstrating that, similar to TALE 9, the specificity of the NT-L is maintained within this truncation. The SELEX experiment was also performed with NT-L in the clone #7 truncation that showed that DNA binding specificity was maintained.

TABLE 13 SELEX results with NT-L, clone #2, #6, and #7 NT-L, Clone #2, Library N22TA

NT-L, Clone #6, Library N26TA

NT-L, Clone #7, Library N22CG

The transcriptional activity of the engineered NT-L proteins was then analyzed against a luciferase reporter construct containing two copies of the target sequence. As shown below in Table 14 and FIG. 6A, the engineered NT-L fusion protein (R23570V), containing the engineered 17.5 tandem repeats but otherwise identical to TR13-VP16, is capable of driving potent reporter gene activation, whereas the similar construct with no tandem repeats (R0-VP16) does not activate luciferase. The TALE sequences flanking the full length tandem repeats (N-cap and C-cap) are required for the reporter gene activation as the deletion of either the N-terminal or C-terminal sequence flanking the repeats (nR23570S-dNC and nR23570S-dNC, respectively) abolished the transcriptional activity. The construct termed nR23570S-dNC contained the SV40 nuclear localization signal (n) and the engineered NT-L repeats (R23570) fused to a single p65 activation domain (S). This construct contained only the repeats but no N-terminal or C-terminal sequence from TALE (dNC). The constructed nR23570SS-dNC was same as described for nR23570S-dNC except that it had two p65 activation domains.

As can be seen from Table 14, the highest level of activation of the reporter was found with the R23570V construct. Note that when the NT-L repeats were used in the absence of the N-terminal and C-terminal capping regions, no activation above background was observed in this assay (compare nR23570S-dNC to mock).

TABLE 14 Reporter activation of NT-L fusion Construct Fold Activation nR23570S-dNC 1.96 nR23570SS-dNC 3.77 R23570V 74.46 R0-VP16 1.00 Mock 1.48

Next, the constructs were used to target the endogenous NTF3 gene to see if the engineered fusion protein was capable of activating an endogenous gene in its chromosomal locus in a mammalian cell. In the experiment of FIG. 6B, the engineered NT-L (R23570V), as well as the control constructs (R0-VP16, GFP), were transiently transfected into human 293 cells. After 2 days following transfection, the NT-3 expression level was analyzed by Taqman analysis. As shown in FIG. 6B, expression of engineered NT-L (R23570V) lead to a substantial increase in NTF3 mRNA expression in human 293 cells, whereas expression of control proteins (R0-VP16 or GFP) had no effect on NTF3 expression level. This is the first time that a specifically engineered TALE domain fusion protein has been used in a mammalian cell to activate expression of an endogenous gene.

An additional exemplary construct was made to determine if all 278 residues of the C-terminal regions flanking the TALE repeat domain was required for activity. This additional construct (+95) contained only the first 95 residues of the C-terminal region between the TALE repeat domain and the VP16 activation domain (i.e. C+95 C-cap). FIG. 7 shows a diagram of these two constructs (the +278 construct was referred to as R23570V in FIG. 6) and the effect of these proteins on NTF3 activation at the mRNA and protein levels. Also shown are the SELEX results for the longer of these constructs (containing the +278 C-terminal (or full length) domain). As can be seen in the figure, both TALE transcription factor constructs are able to up-regulate NTF3 expression at both mRNA and protein levels.

Constructs specific for binding in regions in the VEGF, CCR5 and PEDF gene were also generated. As described above, repeat domains were engineered to bind to these targets by the methodology described above. Target sites for these proteins are shown below in Example 7. The proteins contained either 10-repeat or 18-repeat DNA binding domains.

Additionally, a series of truncations were made in the 9.5 repeat NTF3-specific and the 9.5 repeat VEGF-specific TALE DNA binding domains. The truncations were expressed in the TNT Coupled Reticulocyte Lysate system (Promega) and the lysate was used to bind to the DNA fragments as follows. The protein were expressed by adding 5 μL of water containing 250 nanograms of the nuclease fusion clone plasmid to 20 μL of lysate and incubating at 30° C. for 90 minutes. The binding assays were done as described above. Western blots using standard methodology confirmed that the expressed proteins were all equally expressed. The results of the binding assays are shown in FIG. 8. In these experiments, for truncations of the N-terminus, the C-terminal amino acid was held at C+95, while for the C-terminal truncations, the N-terminus was maintained with the N+137 configuration. As can be seen from the Figure, in this assay, maximal binding was observed when the proteins contained at least 134 amino acids on the N-terminal side of the first true repeat, and at least 54 amino acids on the C-terminal side of the half repeat, and interestingly, this was true for both the TALE DNA binding domain targeted to the NTF3 sequence and for the one targeted to the VEGF sequence (compare panels A and B). The truncations around the critical 134 N-terminal position were repeated using a protein where the C-terminus was truncated to +54 (rather than C+95 as described above) and the C-terminal truncations were repeated where the N-terminus was truncated to the +134 position (rather than N+137). The data are presented in FIG. 9 and show a similar drop-off in DNA binding when the C terminus was truncated past +54 and/or when the N terminus was truncated past +134 as was observed in the previous experiment. These data indicate that the minimal caps for optimal binding in this in vitro affinity assay extend to positions N+134 and C+54.

Example 6: Dissection of the TALE Functional Domains Involved in DNA Targeting in Mammalian Cells

In this example, various deletions at N-terminal or C-terminal of TALE13 proteins, as indicated below in Table 15, were generated.

TABLE 15 TALE 13 deletion constructs Construct Name N-cap C-cap R13 N + 137 C + 278 R13-dN N + 8 C + 278 R13-d240N N + 34 C + 278 R13-d223N N + 52 C + 278 R13-d145C N + 137 C + 133 R13-d182C N + 137 C + 95 R13-dC N + 137 C + 22

All constructs were linked to the VP16 activation domain (constructs with VP16 were designated “R13V”) and a nuclear localization signal (constructs with NLS were designated “nR13”), and tested for reporter gene activation from a reporter construct containing 2 copies of predicted TALE13 targets (FIG. 10, top panel).

As shown in FIG. 10, the minimal region that retains robust reporter activation activity in this set of constructs (see Table 15) is R13V-d182C, which lacks 152 amino acids at its N-terminus and 183 amino acids at its C-terminus. The result confirms that R0 region preceding the first tandem repeats and the leucine rich region following the last repeat is provides optimal binding in this assay, whereas the region containing nuclear localization signal, and the native activation domain at its C-terminus is dispensable for DNA-targeting in mammalian cells.

Example 7: Demonstration of Nuclease Cleavage Activity of a TALE Linked to Nuclease Domains

Next, the DNA targeting ability of TALEs in the context of artificial TALE nucleases (TALENs) was evaluated. The DNA targeting domain of TALE13 as defined in Example 6 was linked to nuclease domains to generate a construct named as R13d182C-scFokI, which is the same as R13V-d182C described above, except that two copies of the FokI nuclease domain, linked by 12 copies of GGGS sequence (SEQ ID NO: 127) between the FokI domains, were used to replace the VP16 activation domain. The TALEN construct was then tested for nuclease activity in a single stranded annealing (SSA) based reporter assay (see co-owned US Patent Publication No. 20110014616).

The reporter construct (FIG. 11A, SSA-R13) used in this assay contains the predicted TALE13 target, sandwiched by the N-terminal (GF) and C-terminal part (FP) of the GFP coding sequence. The reporter SSA-R13 by itself cannot drive the GFP expression, but the cleavage at the TALE13 target will promote homologous recombination (HR) among the N- and C-terminal part of GFP to form a functional GFP transgene. In the experiment whose results are depicted in FIG. 11B, the SSA-R13 reporter construct, together with or without (mock) the TALEN construct, was transiently nucleofected into K562 cells as described previously.

Two days following nucleofection, the percentage of GFP positive cells was analyzed by flow cytometry. As shown in FIG. 11B, about 7% GFP positive cells were generated from SSA-R13 reporter plasmid by the TALEN fusions (R13d182C-scFokI), compared to about 1.4% in the control experiment lacking the TALE plasmid (mock), representing a significant increase in the cleavage at TALE13 target in the SSA-R13 reporter.

These data demonstrate that TALE DNA binding domains can be used to generate functional TALENs for site specific cleavage of DNA in mammalian cells.

TALE domain fusions were also constructed using FokI cleavage half domains. For these examples, wild type FokI half cleavage domains were used so that for nuclease activity, a homodimer must be formed from two of the fusions. For these fusions, the TALE13 DNA binding domain was fused to each FokI half domain by cloning the TALE DNA binding domain into a plasmid adjacent to FokI-specifying sequence. In addition, various linkers were tested for use between the DNA binding domain and the nuclease domain. Linkers L2 and L8 were used which are as follows: L2=GS (SEQ ID NO:71) and L8=GGSGGSGS (SEQ ID NO:72). The target sites were cloned into a TOPO2.1 target vector (Invitrogen) with varying gap spacings between each target binding site such that the two were separated from each other by 2 to 22 bp. PCR amplification of an approximately 1 kb region of the target vector was done to generate the target DNAs. The TALE DNA binding domains were also truncated as described previously, and are described using the same nomenclature as described above in Examples 2 and 6. The TALE domain nuclease fusion clones were expressed in the TNT Rabbit Reticulocyte Lysate system by adding 5 μL of water containing 250 nanograms of the nuclease fusion clone plasmid to 20 μL of lysate and incubating at 30° C. for 90 minutes.

The lysate was then used to cleave the target DNAs as follows: 2.5 μL of lysate were added to a 50 μL reaction containing 50 nanograms of PCR-amplified target DNA and a final Buffer 2 (New England Biolabs) concentration of 1×. The cleavage reaction was for one hour at 37° C., followed by a 20 minute heat inactivation stage at 65° C. The reaction was then centrifuged at high speed to separate the target DNA from the lysate, causing the lysate to condense into a pellet in the reaction well. The DNA-containing supernatant was pipetted off and run on an ethidium bromide-stained agarose gel (Invitrogen) to separate intact target DNA from cleaved target DNA. The agarose gel was then analyzed using AlphaEaseFC (Alpha Innotech) software to measure the amount of target DNA present in the large uncleaved DNA band and the two smaller DNA bands resulting from a single cleavage event of the target DNA. The percentage of cleaved DNA out of the total amount of target DNA loaded into the gel represents the percent cleavage in each reaction.

We desired to minimize the flanking regions of the TALE proteins in an effort to pare the fusions down to the specific regions required for efficient binding, reasoning that trimming the extraneous peptide sequence would provide a more constrained attachment of the FokI cleavage domain, which could improve the catalytic activity of the TALENs. The truncations made on the N- and C-terminal ends (SEQ ID NO:73 and SEQ ID NO:369) of the TALE DNA binding domain were made as shown below where the truncation sites are indicated above the amino acid sequence, and the predicted secondary structure (C=random coil, H=helix) is indicated underneath the sequence:

The results of the C-terminal deletion studies are shown in FIGS. 12 and 13. FIG. 12 shows the cleavage of the target sequences by visualizing the cleavage products on ethidium bromide stained agarose gels. In FIG. 12, L2 or L8 indicates the linker used, and the number beneath each lane indicated the by gap between the two target DNA binding sites of the dimer. ‘S’ indicates the presence of only one target DNA binding site such that an active nuclease homodimer cannot form on the DNA. “Pmll” indicates the positive control reaction of cleavage using a commercially-available restriction enzyme (New England Biolabs) of a unique restriction site located in the cloned DNA target sequence next to the TALE binding sites. Cleavage at the PmlI site indicates that the cloned target site exists in the PCR-amplified target DNA and also shows the approximate expected size of cleaved DNA. Blank indicates the negative control TNT reaction without the TALEN encoding plasmid such that no TALEN was produced. The data is depicted in a graphical format in FIG. 13, and shows that the cleavage activity of the protein greatly increases with C+28 and C+39 C-caps for a spacer length of at least 9 bases. These experiments were continued and further C-caps (C−2, C+5, C+11, C+17, C+22, C+25, C+28 and C+63) were constructed. The results are summarized below in Table 16. “Spacer” indicates the number of base pairs between the target sites and “SC” indicates those samples containing only one binding site in the target.

As can be seen from the data presented above, it appears that the proteins become less active in this assay as fusion nucleases when the C-terminus is truncated past approximately C+5.

Cleavage activity of TALE13 nucleases with additional C-terminal truncation points when presented with a target with the indicated spacer was also assessed and results are shown in Table 17 below. “S” indicates that the cleavage target contained a single binding site for TALE13.

Similar to the work done on the C-terminal region of the TALE proteins, deletions were made in the N-terminus as well. The data is presented in FIG. 14 and it is apparent that the activity of the protein with the N-terminal deletions is diminished when truncations are introduced relatively close to the N+137 position. In this Figure, each column is labeled with the corresponding N-terminal truncation and the number of the separate clones that were used. “S” indicates that only a single binding site was present in the target. The sum of these results indicates that the TALENs can be quite active when linked to either FokI half domains or to two half domains which can interact in a single chain configuration, but the length of the N-cap and C-cap has an effect on the DNA cleavage properties of the resulting TALENs.

TALENs were constructed to bind to an endogenous target in a mammalian cell. The 10 repeat NTF3 binding domain was linked to a FokI half domain as described above. In addition, a NTF3 specific partner (rNTF3) was constructed commercially using standard overlapping oligonucleotide construction technology. The synthetic NTF3 partner was made with three variants at the C terminus: C+63, C+39 and C+28, and the TALE DNA binding domain was cloned into a standard ZFN vector which appends an epitope tag and a nuclear localization signal to the C-terminus and the wild-type FokI cleavage domain to the C-terminus. The complete amino acid sequences of the constructs used in these experiments are shown in Example 23.

In addition to the 9.5 repeat NTF3-FokI fusion, and the 18 repeat NTF3-specific NT-L protein, TALENs were also made to target a site specific for the VEGF A gene. This fusion protein contained 9.5 repeat units and was constructed as described above. The 18 repeat NT-L and the VEGF-specific TALENs were also made with either a C terminal truncation of either +28, +39 or +63. These synthetic fusion nucleases were then used in vitro in nuclease assays as above, in various combinations. The substrate sequences are shown below with the capital letters indicating the target binding sites for the various fusions:

Thus, these proteins are active as nucleases in vitro.

These proteins were also used in an assay of endonuclease activity in a mammalian cell using the SSA reporter system described above. A target substrate (shown in FIG. 15A, SEQ ID NOS 342 and 452, respectively, in order of appearance) was cloned in between the disjointed GFP reporter such that cleavage at the NTF3 site followed by resection will result in a whole GFP reporter capable of expression. This substrate contains both a NTF3 target sequence and a target sequence specific for targeting the CCR5 gene. FIG. 15B depicts the results of this experiment using a selection of the NTF3-specific TALE proteins. In this experiment the following NTF3-specific TALEN fusions were used. TALE13C28L2 is the TALE13 derivative described above with a C+28 truncation and the L2 linker. rNT3R17C28L2 is the 17.5 repeat NT3-specific protein (that targets the reverse strand of the DNA with respect to the coding strand of the NT3 gene) with the C+28 truncation and L2 linker. rNT3R17C39L2 is the similar construct with the C+39 C terminus, and rNT3R17C63L2 has the C+63 C terminus. This rNT3R17 DNA binding domain is also termed NT-R. The 8267EL/8196zKK is a control using a pair of CCR5 specific zinc finger nucleases. The data labeled as “-NT3R18C28L8” depicts the results in the absence of the NTF3 specific partner (that targets the forward strand of DNA with respect to the coding strand of the NTF3 gene), while the data labeled as “+NT3 R18 C28L8” depicts the results in the presence of the partner. In this case, the partner is an NTF3 specific protein with 17.5 repeats, truncated at the C28 position and containing the L8 linker. As can be seen in the Figure, the correct pairing of the TALENs leads to efficient cleavage of the reporter gene and thus reporter gene expression.

Example 8: Use of Engineered TALENs to Cleave an Endogenous Locus in a Mammalian Cell

The dimer pairs described above that were targeted to the NTF3 locus (see Table 18) were then tested at the endogenous locus in a mammalian cell. Dimer pairs as shown were nucleofected into K562 cells using the Amaxa Biosystems device (Cologne, Germany) with standards methods as supplied by the manufacturer and subjected to a transitory cold shock growth condition following transfection (see US Patent Publication No. 20110129898).

Cells were incubated at 30° C. for three days and then the DNA isolated and used for Cel-I analysis. This assay is designed to detect mismatches in a sample as compared to the wild type sequence. The mismatches are a result of a double strand break in the DNA due to cleavage by the TALEN that are healed by the error prone process of non-homologous end joining (NHEJ). NHEJ often introduces small additions or deletions and the Cel-I assay is designed to detect those changes. Assays were done as described, for example, in U.S. Patent Publication Nos. 20080015164; 20080131962 and 20080159996, using the products amplified with the following primers: LZNT3-F4: 5′-GAAGGGGTTAAGGCGCTGAG-3′ (SEQ ID NO:80) and LZNT3-1077R: 5′-AGGGACGTCGACATGAAGAG-3′ (SEQ ID NO:81). These primers amplify a 272 bp amplicon from the endogenous sequence, and cleavage by the Cel-I assay will produce products of approximately 226 and 46 bp. While the 226 bp products are visible, the 46 bp products are difficult to see on the gel due to their size. The results are shown in FIG. 16 where the percent genome modification observed is indicated in the lanes that include the Cel-I enzyme. As is evident from the Figure, there are nuclease-induced mutations occurring in these samples, and the samples are reproducible in duplicate (e.g. compare lanes 7 and 22, or lanes 12 and 27).

The studies were repeated with pairs 15, 13, 12, and 10 (see Table 18), using cells that were incubated at either a 37° C. or 30° C. after transfection, and the results are shown in FIG. 17. First, the NT-R TALE DNA binding domain was tested in the SELEX assay as previously described and the results are shown in FIG. 17A. When expressed in K562 cells, these proteins yielded robust gene modification as revealed by the Cel-I assay, with estimated levels of 3% and 9% for the most active heterodimer (pair 12) tested at 37° C. and 30° C. (see FIG. 17B). Moreover Sanger sequencing identified 7 mutated alleles out of 84 analyzed in the 30° C. sample and also revealed a mutation spectrum (minor deletions) consistent with error-prone break repair via non-homologous end joining (NHEJ) (FIG. 17C).

These studies show that TALEN architecture as described herein can drive efficient NHEJ-mediated gene modification at an endogenous locus and in a mammalian cell.

These studies also reveal compositions that may be used to link a nuclease domain to a TALE repeat array that provides highly active nuclease function. The samples were also subjected to deep sequencing at the NTF3 locus. Samples were barcoded with a 4 bp sequence and a 50 bp read length was used on an Illumina Genome Analyzer instrument (Illumina, San Diego Calif.). Sequences were processed with a custom python script. Sequences were analyzed for the presence of additions or deletions (“indels”) as hallmarks of non-homologous end joining (NHEJ) activity as a result of a double stranded break induced by nuclease activity. The results are presented in FIG. 18. In the endogenous locus, there is a 12 base pair gap between the target sequences recognized by these two proteins (see FIG. 18A). As shown in FIG. 18B, there are numerous indels that demonstrate activity against the endogenous NTF3 locus in a mammalian cell. In FIG. 18B, the wild type sequence at the endogenous locus is indicated by “wt”.

Example 9: Targeted Integration into an Endogenous Locus Following TALEN Cleavage

TALE-mediated targeted integration at NTF3 could happen via the HDR DNA repair pathway or via the NHEJ pathway. We designed an experiment to assay TALE-mediated targeted integration at NTF3 based on the capture of a small double-stranded oligonucleotide by NHEJ. We have previously shown capture of oligonucleotides at the site of ZFN-induced DNA double-strand breaks (DSBs). This type of targeted integration was enhanced by (but did not absolutely require) the presence of 5′ overhangs complementary to those created by the FokI portions of the ZFN pair. FokI naturally creates 4 bp 5′ overhangs; in the context of a ZFN, the FokI nuclease domain creates either 4 bp or 5 bp 5′ overhangs. Since the position and composition of the overhangs left by NTF3 TALENs is unknown, we designed nine double-stranded oligonucleotide donors with all possible 4 bp 5′ overhangs in the 12 bp spacer region between the NTF3 TALEN binding sites (NT3-1F to NT3-9R). (see Table 20).

All primers lack 5′ phosphates.

These donors contain two 5′ terminal phosphorothioate linkages and lack 5′ phosphates, and a binding site for the primer Internal F. Complementary oligonucleotides (NT3-1F with NT3-1R, e.g.) were annealed in 10 mM Tris pH 8.0, 1 mM EDTA, 50 mM NaCl by heating to 95° and cooling at 0.1°/min to room temperature. Donor oligonucleotides (5 μL, of 40 μM annealed oligonucleotide) were individually transfected with each of eight different TALEN pairs (A-H, 400 ng each plasmid, see Table 21) in a 20 μL, transfection mix into 200,000 K562 cells using an Amaxa Nucleofector (Lonza) set to program FF-120 and using solution SF.

Cells were harvested three days post-transfection and lysed in 50 μL QuickExtract solution (Epicentre). One microliter of the crude lysate was used for PCR analysis as described below.

We assayed targeted integration of the oligonucleotide donor into the DSB created by the NTF3 TALEN by PCR amplification of the junction created by the oligonucleotide and the chromosome using the Internal F and GJC 273R primers. The expected size of the PCR amplicon based on perfect ligation of the oligonucleotide donor varies depending on the position of the break in the chromosome. As can be seen in FIG. 19, integration of the donor was detected with many combinations of TALEN and donor overhangs. Maximal signal was seen with the CTGG and TGGT overhangs near the center of the 12 bp spacer region. Endogenous chromosomal loci containing donors captured by NHEJ were sequenced and are shown in FIG. 20. The NTF3 target locus (top duplex) and one of the oligonucleotide duplexes used for this study (bottom duplex) are shown and the binding sites for NT-L+28 and NT-R+63 are underlined in the top sequence. The cleavage overhang that will most efficiently capture the duplex (5′ CTGG) is also highlighted. Also shown in FIG. 20B is a second oligonucleotide duplex used for this study. Binding sites for NT-L+28 and NT-R+63 are underlined in the top sequence. The cleavage overhang that will most efficiently capture this second duplex (5′ TGGT) is also shown. The TALENs NT-L+28 and NT-R+63 were then expressed in K562 cells in the presence of the oligonucleotide duplex shown in FIG. 20A. Junctions between successfully integrated duplex and genomic DNA were then amplified using one primer that anneals within the duplex and one primer that anneals to the native NTF3 locus. The resulting amplicons were cloned and sequenced. The “expected” sequence in FIG. 20C indicates the sequence that would result from a perfect ligation of oligonucleotide duplex to the cleaved locus. The box highlights the location of the duplex overhang in the junction sequences. The bottom two lines provide junction sequences obtained from this study. As shown, eleven junction sequences resulted from perfect ligation of duplex to the cleavage overhang, while one junction sequence exhibited a short deletion (12 bp) consistent with resection prior to repair by NHEJ. FIG. 20D shows results from experiments as shown in FIG. 20C except that the oligonucleotide duplex shown in FIG. 20B was used, which has a 4 bp overhang that is shifted by one base relative to the duplex shown in FIG. 20A. The lowest four lines provide junction sequences obtained from this study. As shown, four distinct sequences were identified, which each exhibit short deletions consistent with resection prior to NHEJ-mediated repair.

Example 10: Efficient Assembly of Genes that Encode Novel TALE Proteins

The DNA sequence encoding TALE repeats found in natural proteins is as repetitive as their corresponding amino acid sequence. The natural TALE typically have only a few base pairs' worth of difference between the sequences of each repeat. Repetitive DNA sequence can make it difficult to efficiently amplify the desired full-length DNA amplicon. This has been shown when attempting to amplify DNA for natural TALE-containing proteins. Further analysis of the DNA sequence of the TALE-repeat protein above using Mfold (M. Zuker Nucleic Acids Res. 31(13):3406-15, (2003)) revealed that not only do they have repetitive sequence disrupting efficient amplification, but also that they contain very stable secondary structure. In this analysis, 800 base pairs of sequence were analyzed starting at the 5′ end of the nucleic acid encoding the first full repeat sequence. Thus, the nucleic acid sequence analyzed contained approximately 7.5 repeat sequences. Several of these secondary structures are shown in FIG. 21.

These structures can occur between any of the TALE repeats or between repeats that are not adjacent. To provide efficient amplification of DNA sequences containing TALE repeats, introduction of silent mutations to disrupt this secondary structure and bias the reaction towards the full-length amplicon were made in the regions of the TALE repeats that serve to stabilize the secondary structure. Primers were then made to allow efficient amplification of the TALE sequence or interest. The PCR amplification product was then sequenced for verification and cloned for use in fusion proteins. In addition, silent mutations were made in the TALE nucleotide sequence for codon optimization in mammalian cells. Similar codon optimization can be used for optimal expression in other host cell systems (e.g. plant, fungal etc.).

Example 11: Method for Rapid Construction of Genes Encoding TALE Fusion Proteins

To allow for the rapid assembly of a variety of TALE fusion proteins, a method was developed to create an archive of repeat modules which could be linked together to create a TALE DNA binding domain specific for nearly any chosen target DNA sequence. Based on the desired target DNA sequence, one or more modules are picked and are retrieved via a PCR based approach. The modules are tandemly linked and ligated into a vector backbone containing the fusion partner domain of choice.

Modules containing four TALE repeat units were constructed with specificity for each of the 256 possible DNA tetranucleotide sequence (for example, one module for the AAAA target, one for AAAT etc.). In addition, modules were also created for all 64 possible DNA trinucleotide targets, all possible 64 dinucleotide DNA targets as well as 4 single nucleotide targets. For the dipeptide recognition region (also referred to as an RVD—Repeat Variable Dipeptide), the following code was used: For recognition of Adenine, the RVD was NI (asparagine-isoleucine), for Cytosine, the RVD was HD (histidine-aspartate), for Thymine, the RVD was NG (asparagine-glycine), and for R (comparable specificity for Guanine or Adenine), the RVD was NN (asparagine-asparagine). In addition, in some engineered TALEs, the RVD NK (asparagine-lysine) was chosen for recognition of G because it appeared to give higher specificity for G than NN in some proteins. Furthermore, the penultimate position N-terminal of the RVD (position 11 of the repeat unit) was N or asparagine (typically this position is an S or serine). This module archive can be expanded by using any other RVDs.

The PCR specificity, cloning and manipulation of DNA bearing perfect sequence repeats is problematic. Thus, in order to construct the archive, many natural TALE repeat sequences were analyzed to see where variability in amino acid sequence could be tolerated in an attempt to diversify repeat sequences at the DNA level. The results are depicted in FIG. 22, where letter size is inversely related to observed diversity at a given position: larger letters indicate less tolerance of diversity while smaller letters indicate positions where other amino acids are sometimes observed. For example, at position 1, the first amino acid of the repeat unit, an L, or leucine is essentially invariantly observed. However, at position 4, three different amino acids are sometimes found: an E, or glutamate, an A, or alanine, or a D, or aspartate. In addition, the nucleotide sequence encoding the various repeat modules was also altered to exploit the redundancy in the genetic code such that codons encoding specific amino acids may be interchanged allowing the DNA strand encoding the repeat unit to have a different sequence from another repeat unit, but the amino acid sequence will remain the same. All of these techniques were utilized to pools of modules that could be used to construct engineered TALE DNA binding domains where the interior of the DNA binding domain could recognize any desired target.

To allow the designer to specify the position of the modules, a type II S restriction enzyme was used, BsaI, which cleaves to the 3′ end of its DNA target site. BsaI recognizes the sequence shown below. Also illustrated are the “sticky ends” (SEQ ID NOs: 102-105) of the cleaved DNA left following enzymatic cleavage:

5′ . . . GGTCTCNNNNNN . . . 3′ 5′ . . . GGTCTCN NNNNN . . . 3′ 5′ . . . CCAGAGNNNNNN . . . 3′ 5′ . . . CCAGAGNNNNN N . . . 3′ Recognition site -> After cleavage

As will be appreciated by the artisan, the sequence of the sticky ends is dependent upon the sequence of the DNA immediately 3′ of the restriction recognition site, and thus the ligation of those sticky ends to each other will only occur if the correct sequences are present. This was exploited to develop PCR primers to amplify the desired modules that would have known sticky ends once the PCR amplicons were cleaved with BsaI. The PCR products were then combined following BsaI cleavage to allow ligation of the products together in only the order specified by the user. An assembly scheme to ligate up to four modules that consist of 1 to 16 full TALE repeats is depicted in FIG. 23. The primers used were as follows where the numbering corresponds to that shown in the Figure. While the listed primers are intended to be used to ligate up to four modules, by using the same concept, more primers can be added in order to ligate more than four modules.

Primers:

(SEQ ID NO: 106) T1F-Bsa GGATCCGGATGGTCTCAACCTGACCCCAGACCAG  (SEQ ID NO: 107) T1R-Bsa GAGGGATGCGGGTCTCTGAGTCCATGATCCTGGCACAGT  (SEQ ID NO: 108) T2F-Bsa GGATCCGGATGGGTCTCAACTCACCCCAGACCAGGTA  (SEQ ID NO: 109) T2R-Bsa GAGGGATGCGGGTCTCTCAGCCCATGATCCTGGCACAGT  (SEQ ID NO: 110) T3F-Bsa GGATCCGGATGGGTCTCAGCTGACCCCAGACCAG  (SEQ ID NO: 111) T3R-Bsa GAGGGATGCGGGTCTCTCAAACCATGATCCTGGCACAGT  (SEQ ID NO: 112) T4F-Bsa GGATCCGGATGGGTCTCATTTGACCCCAGACCAGGTA  (SEQ ID NO: 113) T4R-Bsa CTCGAGGGATGGTCTCCTGTCAGGCCATGATCC 

When using this method, the ligation of the BsaI cleaved PCR amplicons can only occur where the 3′ end of the “A” module ligates to the 5′ end of the “B” module, the 3′ end of the “B” module can only ligate to the 5′ end of the “C” module etc. In addition, the vector -backbone that the ligated modules are cloned into also contains specific BsaI cleaved sticky ends, such that only the 5′ end of the “A” module, and only the 3′ end of the “D” module will ligate to complete the vector circle. Thus, position of each module within the engineered TALE DNA binding domain is determined by the PCR primers chosen by the user.

At the current time, DNA target sites for TALE DNA binding domains are typically flanked by T nucleotides at the 5′ end of the target (which is recognized by the R0 repeat) and at the 3′ end of the target (which is recognized by the R1/2 repeat). Thus, the vector backbone has been designed such that the ligated PCR amplicons containing the specified modules are cloned in frame between R0 and R1/2 sequences within the vector. In addition, the vector contains the user specified C-terminal domain type (truncated or not) of the TALE protein and the exogenous domain of choice for fusion partner. In the design depicted in FIG. 23, the exogenous domain is a FokI domain, allowing for the production of a TALE nuclease. The vector further contains sequences necessary for expression of the fusion protein such as a CMV promoter, a nuclear localization signal, a tag for monitoring expression, and a poly A site. This vector can now be transfected into a cell of the user's choice. In addition, the vector can be further modified to contain selection markers, domains or other genes as desired and/or required for different cellular systems.

Example 12: Design and Characterization of Specific Endogenous TALENs

To evaluate the TALEN design method, we sought to demonstrate TALEN mediated gene modification near the position of the delta 32 mutation (shown below in Bold underline) within the human CCR5 gene (see Stephens J C et al, (1998) Am J Hum Gen 62(6): 1507-15). For this study, we designated a cluster of four “left” and four “right” binding sites at the location of delta 32 (see below), which defined a panel of 16 dimer targets (SEQ ID NO:114-123, respectively, in order of appearance).

Within this panel, individual targets were separated by a range of gap sizes—from 5-27 bp. TALEN proteins were assembled using the methods described in Example 11, such that in all proteins described (unless specifically noted), the RVD specifying ‘T’ was NG, for ‘A’ was NI, for ‘C’ was HD and for ‘G’ was NN. Next, two alternative proteins were generated for each target, bearing a C-terminal segment of either 48 or 83 residues. Finally, all pairwise combinations of “left” and “right” proteins (8×8=64 total) were expressed in K562 cells and assayed for modification of the endogenous locus. See Table 22 below (day 3 and day 10):

TABLE 22 Pairwise combinations of activity for CCR5 Δ32-specific TALEN truncations Right Nuclease +28 +63 R549 R551 R557 R560 R549 R551 R557 R560 Day 3 modification levels Left Nuclease +28 L532 <1 <1 <1 <1 <1 <1 <1 <1 L538 2% 21%  2% 3% <1 12%  26% 21% L540 <1 <1 <1 <1 <1 <1  5% <1 L543 <1 <1 10% <1 <1 <1 21% 12% +63 L532 <1 <1 <1 <1 15% 8% <1 <1 L538 <1  6% 30% 24%  <1 5% 27% 21% L540 <1 <1 20% 14%  <1 <1 24% 19% L543 <1 <1 20% 6% <1 <1 12% 24% Day 10 modification levels Left Nuclease +28 L532 L538 3% 15%  3% 3% 5% 21% 18% L540  3% L543 11% 20% 11% +63 L532 11% 4% L538  5% 23% 23%  3% 26% 17% L540 12% 9% 28% 13% L543 16% 5% 12% 15%

Since the target sites contained a variety of gap sizes, data concerning the most active nucleases can also be analyzed with respect to the distance between the two target sites. Shown below in Table 23 is a similar panel to those above in Table 22, except that it shows the gap sizes for the target sites.

TABLE 23 Gap sizes for pairwise combinations R549 R551 R557 R560 L532 16 bp 18 bp 24 bp* 27 bp* L538 10 bp* 12 bp 18 bp 21 bp L540  8 bp* 10 bp* 16 bp 19 bp L543  5 bp*  7 bp* 13 bp 16 bp *indicates pairings where there was <1% gene correction activity as assayed by the Cel I assay (compare to Table 22, +63/+63)

Thus, the data from Table 22 and Table 23 can be compared to determine that the range of gap sizes where these pairs are most active includes 12 to 21 bp but excludes gaps of less than 11 bp or more than 23 bp.

To demonstrate that our TALEN architecture could induce gene editing via the other major cellular DNA repair pathway: homology directed repair (HDR), a second locus within CCR5 (termed locus 162) that had shown promise in prior studies as a potential safe-harbor for transgene integration (see Lombardo et at (2007) Nat Biotechnol 25: 1298-1306) was targeted. Four “left” and four “right” right binding sites were designated (see below, SEQ ID NO:123-131), and two alternative TALENs were constructed for each (the +28 and +63 variants), and the +28/+28 and +63/+63 pairings were screened for NHEJ-mediated gene modification using the Cel-I assay (SEQ ID NOs: 370-379, respectively, in order of appearance).

As shown below in Table 24, of the 24 pairs tested, 16 yielded detectable modification at levels of up to 21%.

Next, the two most active pairs (L172+28/R185+28 and L161+63/R177+63) were introduced into K562 cells with a donor DNA fragment designed to transfer 46 bp insertion bearing a BglII restriction site into the targeted locus. The donor sequence used is shown in Example 23.

Following insertion, the incorporated tag donor sequence was 5′-5′ TCATCTTTGGTTTTGTGGGCAACATGCTGGTCATCCTCATCTAGATCAGTGAGTATG CCCTGATGGCGTCTGGACTGGATGCCTCGTCTAGAAAACTGCAAAAGGCTGAAGAG CATGACTGACATCTACCTGCTCAAC-3′ (SEQ ID NO:177) with the unique BglI restriction site being underlined.

If donor insertion occurred via HDR, the region containing the insert site can be PCR amplified and then subject to BglI digestion, as is shown below where the top strand shows the sequence of the target site (SEQ ID NO:133) and the bottom strand (SEQ ID NO:134) shows the sequence of a target had the tag donor inserted. The underlined sequence in the top strand shows the TALEN binding site while the underlined sequence in the bottom strand shows the BglI restriction site:

As shown in FIG. 24, PCR products of clones containing an insert had two fragments following BglI digestion. The PCR and BglI digestion scheme is shown in FIG. 24A, while the results are shown in FIG. 24B, and revealed highly efficient editing. Thus, our TALEN architecture induced efficient gene modification via HDR at an endogenous locus.

Example 13: Examination of Gap Spacing Preferences for Selected TALEN Architectures

To examine the gap spacing preferences of two preferred TALEN architectures (C+28 C-cap or C+63 C-cap pairs), all TALEN pairs containing a pairing of C+28/C+28 or C+63/C+63 were sorted for activity according to gap spacing. The results are shown in FIG. 25, and demonstrate that the smaller TALEN proteins, the C+28/C+28 pair, have a more constrained gap spacing preference and are most active on targets wherein the target sequence are separated by gaps of 12 or 13 base pairs. Conversely, the larger TALEN proteins, the C+63/C+63 pairs, shown in FIG. 25B, are active on targets containing gap spacings ranging from 12-23 base pairs.

Example 14: Systematic Mapping of Compositions that May be Used to Link a Nuclease Domain to a TALE Repeat Array that Provide Highly Active Nuclease Function

Systematic mapping of compositions that may be used to link a nuclease domain to a TALE repeat array that provide highly active nuclease function. Initially, one TALEN pair was chosen against a single target with a defined gap spacing between the two binding domains. The TALEN pair chosen was that described in Example 12 as the L538/R557 pair which were specific for the CCR5 gene and had an 18 base pair gap spacing. The deletions were made as described above such that a truncation series resulted in C-caps from C−2 to C+278.

These truncations were then used to analyze nuclease activity in K562 cells using the Cel-I mismatch assay. The results (% NHEJ) are shown below in Table 25 and FIG. 26.

TABLE 25 Nuclease activity for fine mapping C-terminal truncations C-cap Activity 30° Activity 37° C − 2 18.2% 4.6% C − 1 14.3% 3.3% C + 5 2.1% 2.7% C + 11 5.8% 3.2% C + 17 9.2% 5.9% C + 22 5.7% 2.9% C + 28 10.4% 3.0% C + 63 48.8% 24.0% C + 79 20.7% 5.0% C + 95 9.8% 2.4% C + 123 14.0% 4.2% C + 153 8.1% 0.7% C + 183 7.0% 0.8% C + 213 3.1% 1.7% C + 231 2.2% 0.8% C + 278 8.4% 0.7%

The data demonstrate that the peak activity for this nuclease pair against this endogenous target occurs when the C-cap is approximately C+63, in other words, when the peptide LTPEQVVAIASNGGGRPALESIVAQLSRPDPALAALTNDHLVALACLGGRPALDAVKKG LPHAPALIKRTNRRIPERTSHRVA (SEQ ID NO:451) is used to link the array of full-length TALE repeats to the FokI cleavage domain. In this experiment, the nucleases were tested in K652 cells as before and the cells were incubated either at 30° C. or 37° C. The rough estimate of the activity ratio of the C+63 C-cap compared to the C+278 was greater than 20 times in the 37° C. degree incubation and greater than 6 times for the 30° C. incubation.

To more finely characterize those compositions that may be used to link a nuclease domain to an array of full-length TALE repeats that enable highly active nuclease function at an endogenous locus, additional truncations were constructed. A fine series of truncations was assembled comprising 30 C-caps: C−41, C−35, C−28, C−21, C−16, C−8, C−2, C−1, C+5, C+11, C+17, C+22, C+28, C+34, C+39, C+47, C+55, C+63, C+72, C+79, C+87, C+95, C+109, C+123, C+138, C+153, C+183, C+213, C+231, and C+278. Note that our C-cap notation starts at residue −20. Thus C−41, C−35, C−28, and C−21 indicates a construct completely lacking a C-cap and with 20, 14, 7, or 0 residues removed from the C-terminus of the last full 34-residue TALE repeat. Pairs of the constructs were tested against the appropriate target sites with the following gap spacings between target sites: 0, 2, 4, 7, 10, 14, 18, 23, 28, and 34 base pairs. The pairs were tested against a reporter gene in an SSA assay as well as in a mammalian cell against the endogenous locus. The C-caps are illustrated below where the illustration starts at the last full repeat of a TALE DNA binding domain and shows the points towards the C terminus.

The target sites for the experiment are shown below, illustrating the pair with a 7 bp gap spacing. Note that the -C−16, C−21, C−28, C−35, and C−41 C-cap constructs remove the RVD in the half repeat for each TALEN in the pair and such constructs effectively have a 9 bp gap spacing for the same target DNA sequence. Target sites for all the other gap spacings tested were constructed by either removing base pairs between the targets or by inserting additional base pairs, depending on the gap spacing to be tested (SEQ ID NOS 445-450, respectively, in order of appearance):

The genes encoding the TALEN proteins were assembled as described in Examples 11 and 12 and evaluated by Cel-1 assays. The data are presented below in Table 26A. As shown, the TALE-proteins as described herein can tolerate C-terminal truncations relative to full-length TALE-proteins, including truncations extending into a half repeat and TALE repeat domain itself without complete loss of functionality against an endogenous locus.

In addition, the C-terminal truncations were tested against a reporter gene in the DLSSA assay as described below in Example 19. In these experiments, four pairs of CCR5-specific TALENs were used in the reporter system where the target site of these pairs was built into the DLSSA reporter plasmids. The binding sites of the four TALENs are shown above and the TALENs were used as four pairs, L543+R551 (Pair 1), L538+R551 (Pair 2), L543+R557 (Pair 3)L538+R557 (Pair 4). Gap spacings were varied by insertion or deletion of nucleotides between the binding sites for the pairs. The data are presented below in Table 26 B-E where numeric value indicates the relative fluorescence detected by the DLSSA assay and thus the degree of cleavage. All samples were normalized to a control TALEN pair whose binding site is also present on the DLSSA insert (positive control). Negative control is the assay performed in the absence of TALENs. The reporter #4 has the exact DNA binding sequence and the same gap sequences as the endogenous sequence, and thus can be compared with the Cel-I data at the endogenous locus. The DLSSA data of the four TALEN pairs from reporter #4 is shown in Table 26A. These data illustrate a general correlation between the results found with a reporter system and those observed on an endogenous target are close and thus the reporter system is useful as a screening tool for candidate nucleases to test in any endogenous assay. This is a useful tool when working in systems with precious model cells or when the intended target cell type is either not available or difficult to be used for screening purpose. This is also useful tool to develop and to optimize TALEN technology platform when the target sequences are not available in endogenous genome. Active nucleases can be identified by DLSSA and then ported into the endogenous system for final evaluation.

Thus, the Cel-I and DLSSA results indicate that these proteins have substantial and robust activity when the appropriate C-cap is used and an N-cap is present. Further, gap spacings may play a role in the maximum activity observed with smaller gap spacings being active with a smaller subset of C-terminal truncations as compared to larger gap spacings. We also note that the relative DLSSA activity does not appear to be linearly related to the endogenous activity for the same TALENs obtained at the same temperature (37 degrees Celsius). The reporter results yield a significantly higher relative activity for constructs with C+153, C+183, C+213, C+231, and C+278 C-caps than observed at the native endogenous locus of human cells. Thus activity in reporter systems, even reporter systems in mammalian cells, does not necessarily predict the activity at the native endogenous in mammalian cells.

Example 15: Novel (Atypical) RVDs

Alternative (atypical) RVDs were explored to determine if other amino acids at the positions that determine DNA binding specificity could be altered. A TALE binding domain was constructed whose binding activity was shown by SELEX and ELISA to be sensitive to a mismatch at the middle position. This protein bound the sequence 5′-TTGACAATCCT-3′(SEQ ID NO:178) and displayed little binding activity against the sequences 5′-TTGACCATCCT-3′ (SEQ ID NO:179), 5′-TTGACGATCCT-3′ (SEQ ID NO:180), or 5′-TTGACTATCCT-3′ (SEQ ID NO:181) (ELISA data shown in FIG. 27). These targets are referred to as the CXA targets denoting the middle triplet nucleic acid, where X is either A, C, T or G.

This TALE backbone was then used to characterize the DNA-binding specificity of alternative RVDs (amino acids 12 and 13) for the TALE repeat that targets the base at the 6^(th) position. The two codons that encode this RVD were randomized and clones were screened by sequencing to ensure that the complete repeat units were present. Correct clones were then analyzed by a DNA-binding ELISA against four versions of the target sequence wherein each sequence had either an A, C, T or G at the position the novel (i.e., atypical) RVD would interact with (i.e. TTGACAATCCT (SEQ ID NO:178), TTGACCATCCT (SEQ ID NO:182), TTGACTATCCT (SEQ ID NO:183) or TTGACGATCCT (SEQ ID NO:184)). Results from these studies are shown below in Table 27A and demonstrate that this assay identified that the RVD VG can specifically interact with T, RG can interact with T, TA can interact with T and AA can interact with A, C and T.

Following these initial studies, an analysis was done with all potential RVD combinations and several were identified with high activity and specificity. In addition, RVDs were identified that bound equally well to all bases tested. The data are presented in numeric format below in Table 27B and also in FIG. 28. In the data shown below, all data was background corrected by subtracting the background ELISA signal and then normalized to the average value of NI with the CAA site, HD with the CCA site, NN with the CGA site, and NG with the CTA site.

This data is also presented in FIG. 28 where the data is shown in a 20×20 grid. The first amino acid of the RVD (position 12) is indicated to the left of the grid and the second amino acid of the RVD (position 13) is indicated above the grid. The size of the letters A, C, G, and T in each grid is scaled based on the square root of the normalized ELISA signal for the CAA site, CCA site, and CGA site and CTA site respectively. The boxed RVDs indicate frequently occurring natural RVDs found in TALE proteins encoded by Xanthomonas. Many RVDs have improved DNA binding properties with respect to the naturally occurring HD, NI, NG, NS, NN, IG, HG, and NK RVDs. Exemplary novel RVDs and their cognate nucleotide bases include where N represents positive interaction with all bases:

A: RI, KI, HI

C: ND, KD, AD

G: DH, SN, AK, AN, DK, HN

T: VG, IA, IP, TP, QA, YG, LA, SG, HA, NA, GG, KG, QG

N: KS, AT, KT, RA.

Studies were also undertaken to purposely alter the RVD sequences to specific sequences hypothesized to be candidate novel binders through an analysis of the known RVDs. Thus, the following RVDs have been tested:

RVD Intended target NV, NT, NL, HI, SI, LI A HE, NE, SE, ND, SD, LD C HR, NR, SR, HH, NH, SH, G HN, HK, SN, SK, LN, LK NP, NA, HA, HG, SG, LG T

Oligonucleotides were made to allow the specific alteration of the TALE construct described above. These specific oligonucleotides are then cloned into the expression vectors and assembled as described in Example 11, and resultant protein extracts are analyzed by DNA-binding ELISA and SELEX to determine the binding characteristics of the RVDs.

Twelve of these TALE DNA binding domains comprising the atypical RVDs were subjected to SELEX analysis as described above. The results from the SELEX analysis are shown below in Table 28. In the table, the data for the natural RVD (in bold in the ‘RVD’ column) is presented along with the exemplary novel RVD, and show that in many cases, the novel RVD demonstrates equal or greater preference for the targeted bases as compared with the natural RVD.

TABLE 28

These RVDs were then tested for activity in the context of a full length TALEN. A CCR5-specific 18 repeat TALEN was produced with all novel RVDs for comparison with the CCR5-specific TALEN described in Example 12. The target sites for this TALEN pair is reshown below. The 101041 TALEN monomer was the partner that was modified while the 101047 partner was left with all natural RVDs (SEQ ID NOS 462 and 463, respectively, in order of appearance):

In addition, CCR5-specific TALENs comprising both typical and novel (atypical) RVDs were also constructed in CCR5 specific TALENs in which novel RVDs were substituted of all one type, for example, all RVDs recognizing ‘T’ or ‘A’. The code described previously in Examples 11 and 12 for the typical RVDs was used, i.e. A=NI, C=HD, G=NN, T=NG. For the novel RVDs, the following were tested in this initial analysis: A=HI, NI or KI; C=ND, KD, cND; G=SN, AK, DH, cHN, KN; T=TP, IA, VG, SGgs (SEQ ID NO:464), or IP. When lower case letters are used, these indicate alterations of the positions adjacent to the RVD positions, for example “cND” indicates that positions 11, 12 and 13 in the repeat unit were altered. For these studies, candidate RVDs were chosen by the data presented in Table 27B and used to create proof of principal proteins. Additional TALE proteins may be constructed using alternative atypical RVDs from the entire set. In addition, atypical RVDs may be chosen such that a mixture of RVDs specifying a base may be created (e.g. one TALEN protein may be constructed using both TP and IA RVDs to specify ‘T’ in different positions).

The RVD sequences for the repeat units are shown below in Tables 29A-29C and all mutated positions are indicated in bold font.

These novel TALENs were then tested for cleavage activity against the endogenous CCR5 locus at 30 and 37 degrees, and analyzed by the Cel-I assay as described previously, and were shown to be active at inducing NHEJ (e.g. see FIG. 30). Note that the unlabeled lane represents a non-functional TALEN construct with a frame shift mutation.

The results show that the novel (atypical) RVDs are capable of cleaving DNA when in used in TALEN proteins in which each TALE-repeat unit includes a novel RVD, as well as in type substituted or singly substituted TALENs.

Example 16: Novel TALE C-Terminal Half Repeats

The majority of natural TALEs use the NG RVD in the C-terminal half repeat to specify interaction with a T nucleotide base. Thus, generation of novel C-terminal half repeats was investigated to allow for the expansion of TALE targeting. TALENs targeting the Pou5F1 and PITX3 genes were used as backbones, and the RVD within the C-terminal half repeat (C-cap amino acids C−9 and C−8) was altered to specify alternate nucleic acids. In these mutants, the NI RVD was inserted to recognize A, HD for C, NK for G and the control was NG for T. The TALENs used contained between 15 and 18 RVDs and targeted a variety of target sequences in these two genes.

The results are shown in FIG. 29 and demonstrate that the RVD position in the C-terminal half repeat can be engineered to interact with nucleotide bases other than only T, or can be designed to recognize all bases equally. The lane assignments, target sequences, and % NHEJ as measured in this Cel-I assay are shown below in Table 30.

Example 17: Identification of Optimal Target Sequences

To determine optimal target sequences, and thus optimal TALEN protein design, an in silico analysis was done using the results from multiple SELEX assays to determine i) the best target for the R1 repeat (N-terminal repeat) unit and ii) how specific RVD repeats behave in the context of their neighboring repeat units in dimer and trimer settings. In these studies, the NI RVD was used to recognize A, HD for C, NN for G, and NG for T.

Results are summarized in Tables 31, 32 and 33. The values in Table 31 are log-odds scores calculated as the logarithm (base 4) of the ratio between the observed frequency of the targeted base and the frequency of that base expected by chance (i.e. 0.25). A score of 1.0 would indicate that the targeted base was observed 100% of the time (i.e. 4 times more frequent than expected by chance), a score of 0.0 would indicate that the targeted base was observed 25% of the time, and a negative score would indicate that the targeted base was observed less than 25% of the time. The values in Table 31 were calculated from the average base frequency for the appropriate positions of a data set consisting of SELEX data from 62 separate TALE proteins. The values labeled “R1 RVD” refer to the N-terminal TALE repeat (and cognate position in each binding site). The values labeled “R2+ RVD) refer to all other RVDs (and cognate positions in each binding site). This data indicates a dramatic different in the specificity of TALE repeats bearing HD, NN, and NG RVDs at the N-terminal position versus all other positions.

The values shown in Tables 32 and 33 represent the change in those log-odds scores determined for each base independently versus the score in either the dimer (Table 32) or trimer (Table 33) setting and were determined from SELEX data for 67 separate TALE proteins. Thus the −0.12 value for an NN RVD adjacent to an HD RVD (with the NN RVD closer to the N-terminus of the construct and the HD RVD closer to the C-terminus of the construct) indicates that the sum of the log-odds scores for both positions in the dimer was 0.12 less than would be expected if these two RVDs behaved independently of each other. Similarly, the −0.34 value in Table 33C indicates that an NN RVD flanked on the N-terminal side by a second NN RVD and flanked on the C-terminal side by an HD RVD indicates that the NN RVD of interest has a log-odds score 0.34 less than the average value for all NN RVDs. In Tables 32, 33A, 33B, 33C, and 33D, negative values indicate combinations of adjacent RVDs that perform more poorly than if they were completely independent of each other.

These results demonstrate that there is context dependency for optimal repeat unit binding, and indicate that for optimal protein design/target identification, the repeat units are not completely modular. As a whole, these data can be used to propose design rules to optimize both the target selection for a particular TALE and for designing the optimal TALENs. For example, it appears that NI is the least context dependent RVD and the best RVD at the R1 position is NI (e.g. ideally target sites should start with TA to accommodate R0 and R1-NI). It appears that AC, AT, CC, CA, TA, AA are the best dimers to target while GG, GC, AG, TT, CG, GT, and TC are the worst. In terms of triplets, AAC, ATG, GCA, ATA, ACG, and ATC are very good triplets to target while GGC, AGC, TGC, TTT, GGA, AGT, GGT, GGG, TCT, GTC, CTT, and AGG appear to be the worst. Thus, these design rules can be combined to create the optimally binding TALENs. Similarly, SELEX studies with NK, AK, and DK RVDs in Table 28 and additional SELEX studies with NK RVDs (FIG. 17A) indicate that RVDs with lysine (K) at position 13 tend to cause adjacent NI RVDs C-terminal to the NK, AK, or DK RVD to specify G rather than A. Thus design rules determined for typical RVDs and the NK RVDs should also apply to atypical RVDs with the same residue at position 13.

Example 18: Demonstration of TALEN-Driven Targeted Integration in Human Stem Cells

To demonstrate the versatility of the TALEN system, TALENs were used to drive targeted integration in human embryonic stem cells (ESC) and induced pluripotent stem cells (iPSC). Human ESCs and iPSCs were used for the targeted integration of a puromycin donor nucleic acid additionally comprising a restriction site, into the AAVS1 locus where expression of the puromycin marker is driven by the AAVS1 promoter. Donors and methods followed were those described previously in co-owned WO2010117464 (see also Hockemeyer et at (2009) Nat Biotechnol 27(9): 851-857, in which we demonstrated that the spontaneous frequency of targeted integration of such a construct into the AAVS1 locus is below the limit of detection of our assay). Nucleases used were TALENs specific for the AAVS1 locus as described in Example 11, and the target binding site is shown below:

101077 TCCCCTCCACCCCACAGT ggggccactagggacAGGATTGGTGACAGAAAA (SEQ ID NO: 213) AGGGGAGGTGGGGTGTCAccccggtgatccctg TCCTAACCACTGTCTTTT (SEQ ID NO: 214)                                             101079

First, this locus was targeted with a gene trap approach in which the puromycin resistance gene (PURO) was expressed under the control of the endogenous PPP1R12C promoter only following a correct targeting event. Second, the PPP1R12C locus was targeted using an autonomous selection cassette that expressed the puromycin resistance gene PURO from the phosphoglycerate kinase (PGK) promoter. Clones of puromycin resistant cells were grown and screened by Southern blot against restricted DNA using standard methods. The probe used in this experiment was against the PPP1R12C/AAVS1 locus and recognized a sequence that is the small restriction fragment of DNA (and thus had a higher mobility) with incorporated donor. Targeting efficiency was high independent of the donor used, with approximately 50% of isolated clones possessing either heterozygous or homozygous correctly targeted events and carrying the transgene only at the desired locus. This efficiency is comparable to that previously observed with ZFNs. Targeting to the PPP1R12C locus resulted in expression of the introduced transgene. Uniform expression of enhanced green fluorescent protein (eGFP) was observed in hESCs and iPSC when targeted with the SA-PURO donor plasmids that additionally carries a constitutive eGFP expression cassette. Importantly, hESCs that have been genetically engineered using TALENs remained pluripotent as indicated by their expression of the pluripotency markers OCT4, NANOG, SSEA4, Tra-1-81 and Tra-1-60.

TALENs were also designed against the first intron of the human OCT4 gene (OCT4-Intl-TALEN) and the target sequence is shown below in combination with three different donor plasmids:

(SEQ ID NO: 329) 101125: GACCCTGCCTGCTCCT (SEQ ID NO: 330) 101225: CACCTGCAGCTGCCCAG The TALENs utilized a +63 C-cap and used the typical RVDs (NI, HD, NN, and NG to target A, C, G, and T respectively). 101125 comprised 15.5 TALE repeats and 101225 comprised 16.5 TALE repeats. 101225 utilized a half repeat with an NN RVD to recognize the 3′ Gin its target site.

Correct targeting events are characterized by expression of both puromycin and an OCT4 exon1-eGFP fusion protein under control of the endogenous OCT4 promoter. The first two donor plasmids were designed to integrate a splice acceptor eGFP-2A-self-cleaving peptide (2A)-puromycin cassette into the first intron of OCT4, and differed solely in the design of the homology arms, while the third donor was engineered to generate a direct fusion of exon 1 to the reading frame of the eGFP-2A-puromycin cassette. Both strategies resulted in correct targeted gene addition to the OCT4 locus as determined by Southern blot analysis and DNA sequencing of single-cell-derived clones. Targeting efficiencies ranged from 67% to 100% in both hESCs and iPSCs.

To test whether TALENs can be used to genetically engineer loci that are not expressed in hESCs, TALENs were engineered (using the same design and assembly procedure used for 101125 and 101225) to cleave within the first coding exon of the PITX3 gene. The target sequences are shown below:

(SEQ ID NO: 331) 101148: GGCCCTTGCAGCCGT (SEQ ID NO: 332) 101146: CAGACGCTGGCACT

After electroporation, targeting events were evaluated by Southern blot analysis using an external 5′ and an internal 3′ probe. Single-cell-derived clones carrying the donor-specified eGFP transgene solely at PITX3 were obtained on average 6% of the time. Of note, one of 96 hESC clones analyzed carried the transgene on both alleles of PITX3 Exon1 (in WI#3) hESCs demonstrating the successful genetic modification of both alleles of a non-expressed gene in a single step.

These results demonstrate the ability to use TALENs to drive targeted integration into the genome of stem cells.

Example 19: Examples of TALEN Mediated Gene Editing In Vivo

TALEN genome editing in C. elegans. To demonstrate that TALENs could be used in animals for in vivo gene editing, the following experiments were conducted. A TALEN pair specific for the Caenorhabditis elegans ben-1 mutation were delivered as RNA and screened for benomyl resistance as described in Driscoll et at ((1989) J Cell. Biol. 109:2993-3003). The ben-1 mutant phenotype is dominant and visible in 100% of progeny under a regular dissecting microscope. Briefly, wild-type C. elegans hermaphrodites were reared on regular NGM agar plates before injection with mRNAs encoding TALENs targeting ben-1.

The nucleic acids encoding the TALENs were inserted into an SP6 in vitro transcription vector (IVT) using standard restriction cloning procedures. The ICT vector backbone was derived from pJK370 and contains 5′ and 3′ UTR sequences shown previously to support germ-line translation (see Marin and Evans (2003) Development 130: 2623-2632). Production of mRNAs containing 5′ CAP structures and poly A was performed in vitro using the mMessage mMachine® (Ambion) and polyA tailing kits (Ambion) and purified over a Ambion MEGAClear™ column prior to quantitation using a NanoDrop spectrophotometer (Thermoscientific). mRNA injections were performed under a Zeiss Axiovert microscope using a Narishige IM300 injector. Injection of mRNAs were performed according to standard C. elegans DNA injection protocols (see Stinchcomb et al. (1985) Mol Cell Biol 5:3484-3496) with the following differences: the regulator was adjusted such that the pressure from the N2 gas tank was 60 psi. The P_(inject) and P_(balance) measurements were adjusted to 15 psi and 2 psi, respectively. These pressure values are lower than those typically used for DNA injections to allow a more gentle release of fluid into the worm gonad. All mRNAs were injected at 500 ng/μL, and all mRNAs encoding the TALENs were injected as pairs, thus the total mRNA concentration in the needle was 1000 ng/μL.

Following mRNA injection, the animals were transferred to plates containing 7 μM benomyl. F1 self-progeny were screened as young adults by touching the anterior side of the animal. Heterozygous mutant animals respond by reversal using multiple sinusoidal-like movements, whereas wild-type animals are paralyzed and lack this ability. Non-paralyzed F1 animals were either lysed individually for PCR/Cel-I analysis of the target site (as described above), or transferred individually to fresh benomyl plates and homozygotes isolated from non-paralyzed F2 by sequencing over the target site. One TALEN pair, designated 101318/101321, caused reversion of the ben-1 mutation phenotype, and the F1 progeny were found to be resistant to benomyl. Sequence analysis of the benomyl resistant animals revealed two different bona fide indels at the target location. The locus in the target site for this TALEN pair is shown below, and their sequences are shown in Example 23.

These data demonstrate that TALENs are capable of genomic editing in vivo.

TALEN genome editing in rats. Next, TALENs were used to edit the rat genome. The rat IgM-specific TALEN pair 101187/101188 that targets Exon 2 in the endogenous rat IgM gene was constructed as previously described in Examples 11 and 12 above. The target sequence in the rat genome is shown below where the bold and upper case letters indicate the target site for the TALE DNA binding domain and the lowercase letters indicate the gap or spacer region:

Nucleic acids encoding these TALEN pair were then injected into rat embryos as described in Menoret et at (2010) Eur J Immunol. October; 40(10): 2932-41. Nucleic acids encoding the TALENs were injected either as a pronuclear (PNI, DNA) or an intracytoplasmic (IC, RNA) injection at the doses shown below in Table 35.

A percentage of the injected embryos were implanted into pseudo pregnant female rats and resultant newborns were assayed for genome editing. DNA was isolated from the pups resulting from the pronuclear DNA injections and subjected to a T7 mismatch analysis as described in Kim et at (2009) Genome Res. 19(7): 1279-1288. Briefly, PCR was performed using the primer set GJC153F-154R to create a 371 bp PCR product. The primer pair is shown below:

GJC 153F primer: (SEQ ID NO: 453) 5′ ggaggcaagaagatggattc GJC 154R primer: (SEQ ID NO: 454) 5′ gaatcggcacatgcagatct

For this analysis, 100 ng tail gDNA was used which had been isolated by standard practice. Potential heteroduplexes were allowed to form using 5 ul of the PCR product as follows: 2′ at 95° C./95° C. to 85° C. (−2° C./sec)/85° C. to 25° C. (−0.1° C./sec)/4° C. This was then digested with T7 endonuclease I (NEBiolabs ref: M0302L) under the following conditions: 5 ul PCR heteroduplex+1 ul 10×NEB2+0.5 ul T7 endo+3.5 ul H2O/20′ á 37° C. Following digestion, the reaction was run on a 1.2% agarose gel in 0.5×TAE. 7 of the 66 pups analyzed were positive for NHEJ activity by the T7 assay, (shown in FIG. 31) and sequencing revealed the presence of a NHEJ associated indels (e.g. 1 bp deletion in rat 3.3 and a 90 bp deletion in rat 3.4).

TALEN pairs are also used for targeted integration with a nucleic acid of interest into rat cells to generate transgenic animals. The rat cells targeted by the TALEN pair are rat embryonic stem cells, one- or more-celled GFP-containing rat embryos or any rat cell type convertible to an induced pluripotent stem (iPS) cell. The TALEN pair is delivered to the cell and can be plasmid DNA, optimally containing a CAG promoter, mRNA, optimally with a 5′ cap structure and a 3′ poly-adenosine tail, purified protein or viral particles containing nucleic acid encoding the TALEN open reading frames. The donor DNA can single- or double-stranded circular plasmid DNA containing 50-1000 bp of homology on both sides of the break site or single- or double-stranded linear plasmid DNA containing 50-1000 bp of homology on both sides of the break site. The TALEN and donor are delivered by microinjection of rat cells or embryos, transfection of rat cells via electroporation, lipid-based membrane fusion, calcium phosphate precipitation, PEI, etc., incubation with purified nuclease protein (for example, if fused to a cell-penetrating peptide), or infection of rat cells or embryos with a virus. These methods are known in the art. The means of generating a modified rat from the injected or transfected cells or embryos will depend on the delivery method chosen. For embryos, the embryos will be implanted into the uterus of a pseudo-pregnant rat and allowed to come to term as described previously. For modified cells, three methods are possible: a) if the rat cells are embryonic stem cells, rat blastocysts should be injected with the modified rat stem cells. Blastocysts will be implanted into the uterus of a pseudo-pregnant rat and allowed to come to term; b) the cell (or its nucleus) should be microinjected into an enucleated oocyte (somatic cell nuclear transfer) and the resulting embryo implanted into the uterus of a pseudo-pregnant rat and allowed to come to term or c) the cell should be converted to an iPS cell and should be injected into a rat blastocyst. Blastocysts will be implanted into the uterus of a pseudo-pregnant rat and allowed to come to term. Pups are then assayed for presence of the transgene by PCR or any other means known in the art.

TALEN genome editing in plants. TALEN pairs specific for the Z. maize RPD1 and C1 genes were constructed as described above in Example 11 and their target sequences are shown below in comparison with the RPD1 locus (SEQ ID NOs: 382 through 387 and 465, respectively, in order of appearance):

The plant specific TALEN pairs were analyzed in mammalian Neuro 2A cells for activity using the Dual-Luciferase Single Strand Annealing Assay (DLSSA). This is a novel system used to quantify ZFN or TALEN activities in transiently transfected cells, and is based on the Dual-Luciferase Reporter® Assay System from Promega. See, Example 13. The system allows for sequential measurement of two individual reporter enzymes, Firefly and Renilla Luciferases, within a single tube (well). Both of the Firefly and the Renilla Luciferase reporters are re-engineered and the assay conditions are optimized. The Firefly Luciferase reporter construct contains two incomplete copies of the Firefly coding regions that are separated by DNA binding sites for either ZFNs or TALENs. In this study, the 5′ copy is derived from approximately two third of the N-terminal part of the Firefly gene and the 3′ copy is derived from approximately two third of the C-terminal part of the Firefly gene. The two incomplete copies contain about 600-bp homology arms. The separated Firefly fragments have no luciferase activity. A DNA double strand break caused by a ZFN or TALEN pair will stimulate recombination between flanking repeats by the single-strand annealing pathway and then restore the Firefly luciferase function. The co-transfected Renilla Luciferase plasmid provides an internal control. The luminescent activity of each reporter is read on a luminometer. Normalizing the activity of the experimental reporter (Firefly) to the activity of the internal control (Renilla) minimizes experimental variability caused by differences in cell viability and/or transfection efficiency. The normalized value is used to determine the activity of a given ZFN or TALEN pair. This is a useful tool when working in systems with precious model cells or when the intended target cell type is either not available or difficult to be used for screening purpose. This is also useful tool to develop and to optimize TALEN technology platform when the target sequences are not available in endogenous genome. Active nucleases can be identified by DLSSA and then ported into the endogenous system for final evaluation. The active TALEN pairs on the plant targets are shown below in Table 35A.

The TALEN pairs were then delivered via gold-particle bombardment to maize Hi II embryos using standard methods (Frame et al, (2000) In vitro cellular & developmental biology. 36(1): 21-29). In total, approximately 90 pollinated maize embryos per TALEN pair were transformed and allowed to grow for ca. seven days on callus initiation media prior to pooling and freezing in liquid N2 for genomic DNA extraction. Genomic DNA was isolated from 4-6 frozen embryos per bombarded plate using the DNeasy Plant Miniprep kit (Qiagen). Each TALEN target was then amplified by two-step PCR using High-Fidelity Phusion Hot Start II Polymerase (NEB) from pooled genomic DNA consisting of three biological triplicates. In the first round, each site was amplified in a 20-cycle PCR using 400 ng genomic DNA and the primers listed in Table 35B. In the second round, an additional 20 cycles were performed using 1 ul of product from the first PCR round and the primers SOLEXA-OUT-F1 and SOLEXA-OUT-R1 to generate complete Illumina sequencing amplicons. The resulting PCR products were then purified on Qiaquick PCR Purification columns (Qiagen), normalized to 50 nM each, and combined in equal volumes so that a total of eight sites were sequenced in a single Illumina lane. Control amplicons from untreated genomic DNA were submitted in a separate lane. Illumina single-read 100 bp sequencing was performed at ELIM Biopharmaceuticals (Hayward, Calif.).

The sequencing revealed the presence of numerous indels in the cell pools from the TALEN treated embryos as is shown below in Table 36. The details of the sequence analysis are as follows: barcoded sequences derived from TALEN treated Zea maize embryos were pooled together and submitted for 100 bp read-length sequencing on an Illumina GA2 sequencer. Barcoded sequences derived from mock treated Zea maize embryos were pooled together and submitted for 100 bp read-length sequencing on a separate lane of the same Illumina GA2 sequencer. Sequences in each resultant data file were separated by barcode and aligned against the unmodified genomic sequence. A small fraction of the embryos contained a 3 bp insertion in the C1 gene relative to the majority of the embryos. Indels consisting of at least 2 contiguous inserted or deleted bases within a 10 bp window centered on the expected TALEN cleavage sites were considered potential NHEJ events and were processed further. InDels that occurred with similar frequency in both a given TALEN treated sample and the cognate mock treated sample were considered sequencing artifacts and were discarded.

The InDel frequency was similar in all samples (from 0.0087% to 0.0185% or about 1 in 11,000 events to 1 in 5,400 events). This implies that the limiting factor is the biolistic delivery to the maize embryos rather than the TALEN activity. Barcoded sequences derived from TALEN treated Zea maize embryos were pooled together and submitted for 100 bp read-length sequencing on an Illumina GA2 sequencer.

Next, these TALENs are used to drive targeted integration (TI) of any desired DNA of interest into the DSB created by TALENs. TI can be accomplished in monocots or dicots using methods known in the art (see for example Shukla et at (2009) Nature 459:437 and Cai et at (2009) Plant Mol Biol 69:699). Novel plant species may also be generated stably transgenic for a selected TALEN as desired, allowing crossing of the TALEN strain to another in which a mutation is desired, followed by segregation of progeny such that some progeny contain only the desired mutation and the TALEN transgene has been segregated away.

Thus, these examples demonstrate that the novel TALENs of the invention are capable of genomic editing in vivo in plant and animal systems.

Example 20: Alterations of the TALE Repeat Unit

To explore alterations in the TALE repeat unit, sequence from both Xanthomonas and Ralstonia were compared. 52 unique repeat units from Ralstonia were examined to observe residue frequencies at each location, and then these values were compiled. The data are presented below in Table 38 where the amino acids are indicated in one letter code from left to the right and the position on the repeat unit is indicated from top to the bottom, and the RVD positions are indicated in bold:

These repeat units then can be combined with those from Xanthamonas to create unique repeat units. Repeat sequences that are combinations of residues found in Ralstonia repeats and residues found in Xanthomonas residues could yield proteins with improved properties such as increased DNA binding affinity, increased DNA binding specificity, or decreased sensitivity to oxidation. Examples of such repeat unit combinations include, with altered residues indicated in bold and a larger font size:

To explore this possibility, the repeat units shown below in Table 39 were constructed. The table shows a typical Ralstonia repeat unit on the first line, and a Xanthomonas repeat unit on the second. Novel repeats, containing both Ralstonia derived residues and other variations designed to probe the sequence requirements for TALE repeats, are shown on subsequent lines. All differences from the typical Xanthomonas repeat unit on the second line are underlined. Next, repeat units were engineered by varying the positions that are in bold in rows 3-27. These novel, engineered repeat units were then substituted into the system designed to test the novel RVDs in Example 15 and shown in FIG. 27, and the resultant constructs were translated in vitro and used in an ELISA. The target sequence used in the ELISA was the ‘C’ variant described in Example 15 (e.g. TTGACCATCC, SEQ ID NO:182) such that the RVD in all of these novel framework mutants was held constant at HD to interact with C. The ELISA results (average of 3 different experiments) are shown in Table 39 were all normalized to the standard sequence repeat unit sequence.

As can be seen from the ELISA results, the activity of TALE DNA binding domains comprising an engineered (e.g., novel) framework with mutations in positions 2, 3, 4, 6, 7, 8, 9, 10 or 11 are diminished (with mutations in positions 2, 3, 4, 7, and 11 having the most significant effect on binding). In contrast, many of the substitutions in positions 20, 21, 24, 25, 26, and 27 either had a minimal effect on DNA binding or actually increased DNA binding. The largest increases in binding occurred when one or more residues from positions 21-27 in the Ralstonia repeat were substituted into the Xanthomonas repeat.

Hybrid repeat units are combined in series to create novel TALE proteins able to recognize any desired proteins. These novel TALE DNA binding domains are also linked to nuclease domains, transcriptional regulatory domain, or any other active protein domain to cause a measurable result following DNA interaction.

Example 21: Construction of TALE-Zinc Finger DNA Binding Domain Hybrids

Zinc fingers were fused to TALE DNA binding domains to create a hybrid DNA binding domain which was then linked to a nuclease. The target DNA sequences are shown below, and comprise a region surrounding a locus within the CCR5 gene. Shown above and below the binding site are the target binding sites for the TALE DNA binding domain and the zinc finger binding site is shown on the target sequence in Bold underline. The “TAG” sequence in Bold/underline is the binding site for the fourth finger from the CCR5-specific ZFN SBS#8267, while the “AAACTG” sequence in Bold/underline is the binding site for the third and fourth fingers in the CCR5-specific ZFN SBS#8196 (see U.S. patent application Ser. No. 11/805,707). The sequences below show that the zinc finger DNA targets are not contiguous with the TALE DNA binding domain targets on the DNA strand, creating the “inner gap”. Thus, this type of fusion allows the practitioner to skip a region of DNA if desired within the inner gap region. (Full-length sequences disclosed as SEQ ID NOS 454 and 546, respectively, in order of appearance.)

The table below, Table 40, shows the results of the studies. In these studies, one nuclease partner is held constant with an inner gap of either 7, 10, or 13 bases. The partner nuclease is then paired with proteins that comprise an inner gap of between 4 and 16 bases. As is shown in the table, TALE/zinc finger hybrid DNA binding domains can form active nuclease pairs when the inner gaps range from 4 to 16 bases.

Example 22: Construction of a TALE-Integrase Fusion Protein

During the life cycle of retroviruses, viral genomic RNAs are reverse transcribed and integrated at many different sites into host genome, even though there are preferences for certain hot spots. For applications utilizing retroviral vectors, especially gene therapy, the possible carcinogenicity of retroviral vectors due to random integration of engineered viral genome near oncogene loci presents a potential risk factor. To overcome such potential problems, the specificity of viral integrases is re-directed to pre-determined sites by utilizing specific TALE DNA-binding domains. Fusions are made with whole or truncated integrases and with whole or truncated integrase-binding proteins (for example LEDGF for HIV integrase). Additionally, fusion pairs are made where one member of the pair is an integrate fused to one protein (for example protein1) and the second pair is a fusion of a TALE DNA binding domain with another protein (for example protein2) where protein1 and protein2 bind to each other. The fusion pairs are cloned into an expression vector such that the pair is expressed in the cell of interest. For a mammalian genomic target, the fusion pair is expressed using a mammalian expression vector. During expression of the TALEN fusions, a donor DNA is supplied such that the donor is incorporated into the cleavage site following TALEN-induced DNA fusion.

What is claimed is:
 1. A method of generating a genetically modified non-human organism, the method comprising: (a) introducing an mRNA encoding a fusion protein into a gonad, ova or embryo cell of the organism, the fusion protein comprising (i) an isolated, non-naturally occurring DNA-binding polypeptide comprising: two or more TALE-repeat units, the TALE repeat units comprising a repeat variable di-residue (RVD); an N-cap polypeptide, wherein the N-cap comprises no more than residues N+1 to N+137 of a TALE protein; and a C-cap polypeptide, wherein the C-cap polypeptide comprises a fragment of a full length C-terminus region of a TALE protein of no more than residues C-20 to residues C+63 of the TALE protein C-terminal domain, and (ii) a cleavage domain or cleavage half-domain; wherein the fusion protein makes a double-stranded break in an endogenous gene such that the gonad, ova or embryo cell is genetically modified and (b) allowing the gonad, ova or embryo cell to mature into an adult organism, thereby generating a genetically modified non-human organism.
 2. The method of claim 1, wherein the organism is a plant.
 3. The method of claim 1, wherein the organism is a worm or a mammal.
 4. The method of claim 1, wherein the organism is a mammal.
 5. The method of claim 1, wherein genetic modification occurs via non-homologous end joining (NHEJ).
 6. The method of claim 1, wherein the genetic modification comprises a deletion.
 7. The method of claim 1, wherein the genetic modification comprises an insertion.
 8. The method of claim 7, wherein the insertion comprises an exogenous nucleic acid.
 9. The method of claim 1, wherein at least one TALE-repeat unit comprises an atypical repeat variable di-residue (RVD).
 10. The method of claim 9, wherein the protein comprises an atypical RVD as shown in Tables 27A or 27B.
 11. The method of claim 1, wherein the C-cap comprises a TALE repeat domain.
 12. The method of claim 1, wherein the cleavage domain or cleavage half-domain is from a TypeIIS endonuclease.
